Excel .xlsx files up to 20 MB. The free check reads up to 5,000 formulas. We do not take .xls or .xlsm files: older formats and macros are a risk we will not open.
We have not checked this file
Your file is deleted as soon as the check finishes. What is in your cells is never stored, never logged and never used to train anything.
