The health check for your Excel file

Drop a workbook: within seconds, see what weighs it down, what makes it fragile and what it leaks. Every problem comes with its fix, and the fixed file is read back before it is offered.

What this tool does

What it does not do: Excel 2007 and later workbooks (.xlsx, .xlsm). An old .xls file is not read; a password-protected workbook is, once its password is typed, and a workbook whose sheets alone are protected is read directly.

No file is uploaded. Turn off your network once this page has loaded: the tool keeps working. How to check it yourself.
