Clean a file

What needs fixing in your spreadsheet?

Choose a focused tool, sign in and review the changes before keeping a new copy. Your original file stays unchanged.

Repeated records

Remove Duplicates

Review repeated rows and choose which records to keep. Conflicting values stay visible.

Several values in one column

Mark the pieces on actual records, then review every row that does not fit.

Two lists that disagree

Find added, absent and changed records in a separate comparison report.

One file per region or category

Split XLSX or CSV by column value. Preview group counts, then download separate files or one workbook with a sheet per group.

Match & Merge connects sheets by a shared ID. Review missing and duplicate keys, then add only the fields you choose.

Find the native Excel method that fits your data, with checks for IDs, formulas and values that need closer attention.
