Before you start

Before proceeding with any repairs or troubleshooting steps, create a backup copy of your original Excel workbook to prevent permanent data loss during the recovery process.

Solution 1Recommended

Test with a Clean Workbook and Safe Mode

Determine if the issue is caused by specific file corruption, active macros, or conflicting Excel add-ins by isolating the environment.

By testing a fresh file and launching Excel without background add-ins, you can quickly identify whether the error stems from the workbook itself or a system configuration problem.

1
Create a test workbook

Open Excel, create a new blank workbook, and insert a simple waterfall chart using generic, basic data (do not copy and paste from the corrupted file).

2
Save and reopen

Save this new workbook and reopen it. If the chart remains intact, your original file is likely corrupted.

3
Launch the Run dialog

Press 'Windows + R' on your keyboard to open the Windows Run dialog box.

4
Start in Safe Mode

Type 'excel /safe' into the text field and press Enter to launch Microsoft Excel in Safe Mode, which disables all third-party add-ins.

5
Test original file

Open your original problematic workbook in Safe Mode to see if the waterfall chart is retained without the unreadable content error.

Test with a Clean Workbook and Safe Mode
Safe Mode limitations: If the file works correctly in Safe Mode, the issue is highly likely caused by a conflicting add-in. You will need to disable your add-ins one by one in normal mode to find the culprit.

Frequently Asked Questions

Why does Excel say my file has 'unreadable content'?

This error usually indicates that the underlying XML structure of the Excel file has become corrupted. For charts, this often happens due to conflicting macros, unsupported complex formatting, incomplete save processes, or software bugs in your specific version of Microsoft 365.

Can I recover the waterfall chart after Excel deletes it during a repair?

Unfortunately, no. Once Excel automatically 'repairs' the file by removing the unreadable content, the chart is permanently deleted from that saved version. You will need to recreate the chart from the data or restore the file from a previous backup or version history.

Are waterfall charts supported in older versions of Excel?

Waterfall charts were introduced natively in Excel 2016. If you attempt to open a workbook containing a waterfall chart in an older version like Excel 2013 or 2010, the chart will not display correctly and might trigger compatibility or unreadable content errors.

Does saving as .xlsm cause issues with visualization charts?

While .xlsm is the standard, supported format for macro-enabled workbooks, conflicting VBA code can sometimes corrupt chart objects upon saving. Testing your data by saving it as a macro-free .xlsx file helps identify if a VBA script is the root cause of the missing charts.
