Why Excel Keeps Crashing and How to Fix It

Microsoft Excel 365 crashing the moment you type into a cell is one of the most disruptive Office problems: the file opens, cells are selectable, but any input freezes the window and Excel closes within seconds. In almost every case the cause is local — a faulty add-in, a damaged template, an outdated build, or a corrupted installation — not the workbook itself. Work through the checks below from the least invasive to the strongest before considering a reinstall.

Why Excel 365 Keeps Crashing While Editing Files

When the crash happens, cells can still be selected, but as soon as something is typed or pasted, Excel freezes for a few seconds and then closes. The same workbook may behave normally on another PC, which confirms the issue sits in the local Excel installation or its add-ins rather than in the file.
