Clean up a spreadsheet.
Keep the changes you choose.

Import a CSV or Excel file, choose what to fix, and review the result. Download a clean CSV or a formatted Excel workbook with a record of the changes.

Your file stays in this browser. No upload, account, or AI service is used. The original file stays unchanged.

1. Choose your data

Try the sample, or open a file from your device. Up to 5 MB, 5,000 data rows, and 40 columns. Excel files must use .xlsx.

Import CSV or Excel

2. Choose what to clean

Check the changes you want, then choose Preview cleanup. The sample already has a few choices selected. Your original file stays unchanged.

Remove extra spaces before and after entriesRemove completely blank rowsRemove rows that are identical in every column

Column to change (optional)Change its format toFlag repeated entries in a column (optional)

The repeated-entry check only flags items for review; it does not remove them. Dates that don’t fit your choice stay unchanged. Numbers such as 00123 keep their starting zeros.

3. Review the result

After Preview cleanup, the table shows the cleaned data. Use Original data to compare, or What changed to see the changes and items that still need checking. Download the result in step 4.

4. Download

CSV contains the cleaned data. Formatted Excel adds filters, readable columns, and a separate review log. Downloads contain the results, without spreadsheet formulas.
