Find the problem behind the total
Open a CSV locally, inspect repeated records and untidy amounts, then download a reviewable repaired copy with count-based next steps.
This example runs in your browser without AI. You can also copy a starter to continue in ChatGPT.
Check it. Choose a fix.
Keep the good data.
Find repeated records, untidy cells and amounts that will not add up. Try the editable example, open your own CSV, or paste rows copied from Excel or Google Sheets. Preview the selected changes, then download a copy to check in your spreadsheet.
Bring a small spreadsheet
Open a .csv file or paste rows copied from Excel or Google Sheets. Maximum 1 MB, 5,000 data records and 100 columns. The first record is the header. Excel workbooks (.xlsx) still need to be saved as CSV first.
Edit or paste CSV text or spreadsheet rows
Quoted commas, tabs and multiline notes are welcome. Automatic detects commas or tabs from the first record; if a paste is ambiguous, choose the format explicitly. Editing this text resets the applied result; inspect again when ready.
What needs a look
Choose what changes
The preview follows your choices. Apply them to prepare a download. Headers stay as supplied, and no source file is overwritten.

Take the useful part with you
Apply your choices to enable downloads.
Safe export is always on: formula-like cells receive a leading apostrophe in the download. Ordinary negative decimals remain numeric. The apostrophe may be visible in your spreadsheet.
Your repair report and follow-up checklist
CSV stores values, not workbook formatting or data types. When reopening it, import ID, date and long-number columns as Text if their exact appearance matters. Check the downloaded copy before relying on it.
Next steps
Tailored AI instruction
AI can explain this count-based summary. It does not do the arithmetic or automatically get your CSV.
For the moments like this.
A CSV export needs a careful check before it becomes the working copy. You want to see repeated records, tidy selected fields, and unresolved amounts clearly, then verify the revised file in the spreadsheet application you trust.
What becomes possible
This route is a local CSV utility: it identifies selected changes and unresolved amount cells, prepares a revised download, and gives you a count-based handoff. AI can explain the summary after you choose what to share; it does not get your file or perform the arithmetic.
Put this to work.
Use the starter in ChatGPT or work with Kevin on your own situation.
Try it in ChatGPT
Copy the starter, open ChatGPT and paste it into a conversation. Add only the details you want to share. Nothing is sent automatically.
Review the starter for ChatGPT
ChatGPT access and features depend on your account. Keep private details out until you understand the settings of the service you use.
Choose how you want help.
Get guidance while you do the work, or ask Kevin to scope and deliver an agreed result.
Guidance and finished work are priced separately. You and Kevin agree the scope and price before work begins.
Sources, capability notes and how this example works
This local utility reads the CSV you choose in your browser, shows the workbench findings, and prepares a revised download after you apply your selected repairs. It does not upload your file or call an AI model. Verify the download in your spreadsheet application.
