How to clean up an Excel spreadsheet in one click

  1. Add your Excel or CSV file.
  2. Tick the clean-ups you want: duplicates, spaces, empty rows and columns, numbers, capitalization.
  3. Click Clean and download the corrected file.

Files merged from several sources, exported from software or typed by hand are rarely clean: duplicate customers, blank rows in the middle, “London” followed by an invisible space, amounts aligned left because they are stored as text. The result: failing VLOOKUPs, wrong totals and incomplete pivot tables.

This tool fixes all of that at once. It removes duplicate and empty rows, trims leading, trailing and double spaces, turns numbers stored as text into real numbers, and can drop empty columns. You can also make capitalization consistent: UPPER CASE for codes, lower case for emails, or Title Case for names.

Choose to clean every sheet or only the first one, leaving the others untouched. A summary tells you what was changed. Keep your original file just in case.

One XLSX, XLSM or CSV file up to 300 MB, deleted after 30 minutes.

Frequently asked questions

How do I get rid of duplicates in Excel?

Drop the file, keep “Remove duplicate rows” ticked and click Clean. Rows that are identical in every column are removed; the first occurrence is kept. The other options can stay on or off.

How are duplicates detected?

A row is a duplicate when all its cells match an earlier row; only the first one is kept.

Why don’t my numbers add up?

They are often stored as text. The “Turn numbers stored as text into numbers” option makes them real numbers.

Can I clean just one sheet?

Yes, choose “First sheet only” and the other sheets stay as they are.

Are spaces between words removed?

No, only spaces at the start and end of a cell and doubled spaces are removed.

Is it free?

Yes, free with no sign-up; the file is deleted automatically after 30 minutes.

How do I convert numbers stored as text to numbers?

Tick “Turn numbers stored as text into numbers”. Values like “1 234,50” or “42” typed as text become real numbers you can sum and sort.

How do I remove extra spaces in Excel?

Tick “Trim extra spaces”: leading, trailing and doubled spaces are removed in every text cell.
