Fix Excel Chart Error Caused by Special Characters in Worksheet Names
Question details
The user is unable to create charts in the Excel desktop application when the worksheet name includes certain special characters, such as a Persian comma.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Attempting to insert a chart using data from a worksheet that has special or foreign characters in its tab name.
- Observed behavior
- The Excel desktop application displays an error and fails to generate the chart, whereas Excel for the web successfully creates it.
Before troubleshooting, try creating a quick test chart on a newly created worksheet with a standard English alphanumeric name to confirm the issue is isolated to the special character.
Rename the Worksheet to Remove Special Characters
The fastest way to bypass this software bug is to temporarily or permanently remove the unsupported special character from the worksheet tab.
Since the charting engine in recent versions of Excel desktop struggles to parse certain foreign symbols or special characters (like the Persian comma) in the sheet name, renaming the sheet to use standard alphanumeric characters will allow the chart to generate normally.
Double-click the affected worksheet tab at the bottom of the Excel window to enter edit mode.
Delete the specific special character causing the issue and replace it with a standard alphanumeric character or underscore.
Press Enter to save the new worksheet name. Select your data range and go to Insert > Chart to verify that the error is resolved.
Use Excel for the Web to Generate the Chart
Because the bug only affects the desktop application, you can use Excel for the web to create your charts without having to change your worksheet names.
Report the Bug to Microsoft Support
Reporting your specific scenario helps Microsoft investigate the parsing error and release a patch for the desktop application.

Frequently Asked Questions
Why do special characters in worksheet names cause chart errors in Excel desktop?
This is often caused by a parsing bug in the Excel desktop application where the chart engine fails to correctly reference or escape sheet names containing certain non-standard, foreign, or special characters, such as a Persian comma.
Can I use single quotes around the worksheet name to fix the chart error?
Normally, Excel automatically wraps sheet names containing spaces or special characters in single quotes within formula references. However, if the desktop app has a specific underlying bug with a certain character, this automatic formatting may still fail during the chart creation process.
Will updating my Excel version fix the chart generation issue?
It is possible. Microsoft frequently releases patches for known software bugs. You can check for updates by navigating to File > Account > Update Options > Update Now in your Excel application.
Are macros affected by special characters in sheet names?
Yes. VBA macros referencing worksheet names with special characters can also encounter runtime errors if the character is not supported by the environment or requires specific string escaping within the VBA code.
