How to clean an Excel sheet without losing formulas or formatting
Exported sheets are often messy: empty rows, numbers stored as text, double spaces, repeated rows. Most online cleaners rebuild the whole file and quietly drop your formulas and colours. These tools edit the workbook itself instead.
Clean the data
- Open Clean Excel data and add your .xlsx file.
- Choose what to fix: empty rows and columns, extra spaces, numbers stored as text, or text case.
- Download the cleaned file.
Formulas follow the rows and columns that move, so a total like =SUM(B2:B40) still adds up the same cells. Colours, bold text, merged cells and column widths stay as they were.
Remove duplicate rows
Remove duplicates keeps the first copy of each row. Pick which columns to compare, and optionally put the removed rows on their own sheet so you can check them.
Good to know
- Formatting is kept for .xlsx and .xlsm files. Old .xls, .ods and .csv files keep their values only.
- Merge Excel keeps values, formulas, sheet names and column widths, but not colours or bold.
- Your spreadsheet is processed in your browser and is not uploaded.
