XLSX repair is about structure, not passwords
An XLSX file is a ZIP container with XML parts inside. If the archive index, workbook XML, or shared strings are damaged, Excel may refuse to open it. Repair targets the broken structure so the workbook can load again.
Symptoms we target
Workbook cannot open
Excel says the file is corrupted or unreadable.
Sheets disappear
The workbook opens but some worksheets are missing or broken.
Invalid content error
Excel reports invalid XML or container data.
Partial download
The file was interrupted during transfer and no longer loads.
How our repair flow works
Upload the file
Send the broken file to the repair flow and let the system inspect the internal structure.
Automatic analysis
The service checks the headers, container structure, and repairable data segments.
Pay only if repaired
When the repair succeeds, the file becomes available on the status page.
Repair vs password recovery
Use the right flow before you spend time on the wrong problem.
| Symptom | Solution |
|---|---|
| Excel asks for a password | Use password recovery, not repair. |
| Excel says the workbook is corrupted | Use repair. |
| Workbook opens with missing sheets | Use repair and inspect the recovered structure. |
