The workbook is corrupted in the drawing part that stores the charts on sheet “应收看板”. Excel can open the file, but when saving it rewrites the package, detects the damaged drawing part /xl/drawings/drawing1.xml, and removes it. That is why after repair all charts on that sheet disappear and the message about removed parts appears.
To handle this situation, only supported actions are:
- Try Excel’s built‑in repair on the original (uncorrupted) copy
- In Excel, select File > Open.
- Browse to the original workbook (before it started showing this error).
- In the Open dialog, select the file, click the arrow next to Open, then choose Open and Repair.
- First choose Repair to recover as much as possible. If that fails, choose Extract Data to at least recover values and formulas.
- If the workbook opens normally but errors only after saving
- Work in the original file.
- Immediately save a backup copy before the error appears (for example, with a different name or in another folder).
- If the error appears again, revert to the last saved version:
- Go to File > Open.
- Double‑click the workbook that is already open.
- Click Yes when prompted to reopen; Excel reverts to the last saved version and discards the changes that may have caused corruption.
- If the drawing part remains corrupted
- The removed part
/xl/drawings/drawing1.xml contains the chart objects. Once Excel deletes this part during repair, those charts cannot be restored from that repaired file.
- Use a known good backup that still contains the charts and copy the “应收看板” sheet into a new, clean workbook.
- If no intact backup exists, only the underlying data (not the charts) can be recovered using Open and Repair or Extract Data.
- Preventive measures for the future
- Turn on automatic backup or recovery so that a previous version can be restored if corruption occurs:
- Configure Excel to automatically save a backup copy of important workbooks.
- Configure Excel to automatically create recovery files at intervals.
If repeated corruption continues even in new files, move the workbook to a local disk (not a network drive) and test again. If necessary, try third‑party recovery tools as suggested in the documentation.
