Excel Sales Data Accuracy Validation

@glanegonsalves

Hi, Glane here. I can consolidate your sales spreadsheets using Python and advanced Excel tools such as Power Query, XLOOKUP, and data validation. I’ll verify dates, IDs, SKUs, quantities, prices, taxes, and totals, flag suspicious or missing values without guessing; and reconcile summary figures against line-item calculations. You’ll receive a clean, validated workbook with conditional formatting, traceable formulas, and a concise change log. I can confirm the turnaround time after reviewing the file sizes and master SKU list.

I can turn your multi-source sales files into a consolidated, audit-ready workbook where calculations, SKU mappings, and exceptions are clearly validated before the data reaches your dashboards. Thank you for considering my proposal. I have gone through the requirements in detail. I’ll systematically validate dates, order IDs, SKUs, quantities, prices, tax, and totals, then recalculate line-item values and grand totals to identify discrepancies. I’ll cross-check SKUs against your master list using XLOOKUP or Power Query, flag blanks and suspicious records without guessing, and document every correction or exception in a clear change log. For future uploads, I’ll add appropriate data-validation rules and conditional formatting so common issues are highlighted automatically. Where useful, I can use Power Query, dynamic arrays, and formula-based checks while keeping the final workbook fully compatible with Microsoft 365. I’ll also reconcile summary totals against underlying line-item calculations and perform a final formula/error check. I have uploaded similar completed Excel samples in my profile for reference. With 10+ years of experience, I am a Chartered Accountant (ICAI) and CPA, with strong expertise in Excel, financial analysis, reconciliation, and data validation. For a typical batch, I can provide the first validated version within 1–2 business days, depending on file size and complexity. I’m ready to begin immediately.

Having explicit acceptance criteria — summary totals matching line-item math, no broken formulas, every flagged inaccuracy either corrected with traceable logic or logged — makes this one straightforward to scope and verify once it's done. Approach: consolidate the source files with Power Query (auditable steps, not static paste), recalculate extended prices, totals and tax with formulas so any mismatch surfaces automatically, cross-check SKUs against your master list with XLOOKUP and flag non-matches rather than guessing at corrections, and layer in data-validation rules plus conditional formatting so future uploads catch errors on their own. The change log will separate what was corrected from what's flagged for your review, plus any patterns worth noting. This quote assumes a moderate dataset — a handful of source files, a few thousand rows combined, and a master list carrying SKU, description and price fields to cross-check. If the actual volume turns out to be significantly larger, I'll flag that before proceeding rather than cutting corners on the validation. Happy to start as soon as I have the files and the master list.

Hi, I can validate and clean your sales transaction spreadsheets and provide a consolidated Excel workbook with traceable validation logic. I can handle: • Validation of dates, order IDs, SKUs, quantities, prices, tax and totals • Formula-based recalculation of line totals and grand totals • SKU verification against your master product list using XLOOKUP • Identification and clear flagging of blank or suspicious records • Excel data-validation rules and conditional formatting for future uploads • Power Query where appropriate for repeatable data-cleaning workflows • Final summary totals and consistency checks • Short change log documenting corrections, flagged records and observations I will not guess missing or suspicious values. Anything requiring your review will be clearly marked and documented. I’ll ensure the final workbook has no broken formulas or hidden calculation errors and opens correctly in Microsoft 365/Excel. Turnaround: 1–2 days Fixed Price: ₹1,200 Available to start immediately.

For this project, the important part is making sure every number in the consolidated file can be traced: corrected with visible logic, or flagged for your review, never silently guessed. We would consolidate the spreadsheets in Power Query so the cleaning steps are repeatable, then validate each record: date formats, duplicate order IDs, quantity and price data types, and tax. Extended prices and grand totals would be recalculated with formulas and compared against the source figures in a variance column, so calculation errors and missed tax show up immediately. SKUs would be matched against your master list with XLOOKUP, and anything unmatched, blank or suspicious gets highlighted for you instead of altered. For future uploads, we'd add data-validation rules and conditional formatting that trigger warnings straight away. You'd receive the validated workbook plus a short change log covering what was fixed, what was flagged and any trends noticed, with summary totals reconciled to the line-item math and no broken formulas. The file will open cleanly in standard Excel. Price: 750 INR Timeline: 4 days Send the spreadsheets and master product list, and we'll begin with a data-quality scan to map the issues before any fixes. Regards, VenomP

Hi, I can consolidate and validate your sales files without re-keying the existing data. I’ll standardize the source sheets, recalculate quantity × price, tax and totals, cross-check each SKU against your master list, and flag blanks, duplicates or inconsistent records instead of guessing. I’ll also add practical data-validation rules and conditional formatting so future uploads are easier to check. You’ll receive the cleaned workbook together with a concise change log showing what was corrected, what still needs review, and any recurring issues I find. I have a relevant Excel Data Cleaning & Validation sample on my profile. Before I begin, approximately how many workbooks and rows are involved, and does the same tax rule apply to every source file? I can start as soon as the files are available and deliver within 2 days. Best, Tan

One consolidated, validated sales workbook where every flagged figure is either corrected with traceable logic or listed in a change log, and future uploads warn you right away. What INR 1350 covers: - All source spreadsheets combined with Power Query into one table, so the same steps can be re-run on the next export - Each record checked: dates, order IDs (duplicates and gaps), SKU codes, quantities, prices, tax and totals - Extended prices and grand totals recalculated with formulas next to the originals, with a mismatch column so every difference is visible - SKU codes cross-checked against your master product list with XLOOKUP; unmatched codes flagged, not guessed - Blank or suspicious values highlighted for your review - Data-validation rules and conditional formatting on the input columns for future uploads - A change log sheet: what was fixed, what was flagged, and the trends I noticed - A final check that summary totals equal the line-item math and that no #N/A, #REF! or hidden errors remain At work I wrote and maintained Excel VBA tools for 3+ years, including data-checking macros for files exported from other systems, and I have done QA professionally. This would be my first contract on Freelancer, and this price is for my first review here. Delivered within 3 days after I receive the files and the master product list. One question: is tax calculated per line or on the order total, and at one rate or several? — Suminawa

@veintech

Hi, I can start immediately and complete the validation within 1 day. I’ll consolidate the sales files, verify dates, order IDs, SKUs, quantities, prices, tax and totals, and recalculate the figures with traceable Excel formulas. I’ll also cross-check SKUs against your master list, clearly flag missing or suspicious values instead of guessing, and add data-validation rules and conditional formatting so future uploads are easier to verify. The final delivery will include a clean validated workbook plus a concise change log showing what was corrected and what still needs review. I can start as soon as you share the source spreadsheets and master SKU list.

@Maanie786

Hello. I understand the critical need for accurate sales data before it feeds into your dashboards. Ensuring that every entry is consistent and validated is essential for reliable reporting. I have extensive experience in data cleaning and validation, specifically with Excel. I will meticulously examine each column, recalculate totals, and cross-check SKU codes against your master list. Using tools like Power Query and dynamic arrays, I can efficiently streamline the process while ensuring that any discrepancies are clearly flagged for your review. I typically deliver projects like this within three days, depending on complexity. I look forward to discussing your specific needs further and how I can help ensure your data integrity. With regards, Maanie

@dennisv39

Hi, I can deliver the validated workbook within 1 day. My approach: Power Query to consolidate the source sheets, then formula checks on every record (quantity x price, tax, line and grand totals recalculated), XLOOKUP against your SKU master list, and clear flags for blank or suspicious values instead of guesses. On top I add data-validation rules and conditional formatting so future uploads warn immediately. You get the final workbook plus a short change log: what was fixed, what was flagged for your review, and any patterns I noticed. Everything opens cleanly in standard Excel 365. Best, Dennis

@freddyleonardoc

I can consolidate and validate your sales spreadsheets without manual re-keying. I would load the files with Power Query, normalize dates, order IDs, SKU codes, quantities, prices, tax and totals, then recalculate extended prices and grand totals with formulas and compare them against the original figures to catch calculation or tax errors. I would cross-check SKUs against your master product list, flag mismatches, and clearly mark blanks or suspicious values for your review instead of guessing. Finally, I would add data-validation rules and conditional formatting for future uploads, and deliver the validated workbook plus a short change log. I review every formula and figure against the source before delivery. How many spreadsheets and rows are involved?

@goranp1

Hi, I can help you clean, consolidate, and validate your sales data with a strong focus on accuracy and traceability. My background includes data quality review and validation, so identifying inconsistencies and documenting them clearly is a familiar part of my work. I would first audit the datasets for duplicates, missing or suspicious values, inconsistent dates, IDs, SKUs, quantities, prices, and tax fields. I’ll then cross-check SKU codes against your master list and independently recalculate line totals and summary totals to identify discrepancies. I can also use Python/Pandas alongside Excel for systematic validation, while ensuring the final deliverable is a standard Excel workbook with appropriate validation rules and conditional formatting. Any questionable values will be flagged rather than guessed, and I’ll provide a short change log explaining what was corrected, what was flagged, and any patterns found. Turnaround: approximately 1–2 days after reviewing the size and structure of the files. I’m available to start immediately. Best regards, Goran

@jackburke27

I can consolidate and validate your sales spreadsheets into one clean Excel workbook with a clear audit trail of what was corrected and what was flagged for review. I’ll check the key fields across all source files, recalculate line totals and taxes, cross-reference SKU codes against your master product list, identify blanks or suspicious values, and add Excel data-validation rules and conditional formatting so future uploads are easier to review. I’ll also make sure the final summary totals reconcile back to the underlying line items, with no broken formulas or hidden errors, and include a short change log explaining the corrections and flags. I can start immediately and complete a normal-sized batch within 1 day.

@oraclepicksa

I can consolidate the sales spreadsheets, validate the existing figures, and clean the workbook without re-keying the source data. I will flag inconsistencies clearly and return the checked file within 3 days. Which columns or validation rules are most important for the dashboard? Denzell

@denisochkaua

I can consolidate your sales files and validate dates, IDs, SKUs, quantities, prices, taxes, and totals against the supplied master product list. I will use traceable formulas to recalculate line items and summaries, flag ambiguous or missing values for your review, and add data validation and conditional formatting for future uploads. You will get a standard Excel workbook and a concise log of fixes and unresolved flags. I can begin when the files arrive and target two days for a modest-size set, with the deadline confirmed once I see the row count. I will test that totals tie to the source rows and no broken formulas remain. My Freelancer profile is new and I will not guess at questionable values.

@rubeenography

Hi, Your requirement is a strong match for my experience in Excel-based data validation, reconciliation and reporting automation. I have 15+ years of enterprise operations experience, including building Excel solutions for reconciliation, validation, reporting and governance. I would approach this as a data-quality control exercise rather than simply cleaning the spreadsheets. I can consolidate the source files, validate dates/IDs/SKUs/quantities/prices/tax/totals, recalculate the expected values, cross-check SKUs against the master list, and clearly separate genuine errors from items that require your review. For repeatability, I can use Power Query, XLOOKUP and Excel validation/conditional formatting so future uploads can be checked using the same logic rather than repeating the process manually. You will receive the validated workbook together with a concise change log showing what was corrected, what was flagged, and the key data-quality issues identified. I can start immediately. Once I see the source files and master SKU list, I can confirm the exact effort and turnaround. Regards, Rubeen Khan
