Fix Converted PDF to Excel Not Opening Due to Font Limit Error
Question details
The user is unable to open an Excel file that was converted from a PDF because of a Microsoft Excel font limitation error.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Opening a newly converted Excel spreadsheet generated from a PDF file.
- Observed behavior
- Microsoft Excel displays the error message "No more new fonts may be applied in this workbook" and fails to open or properly display the converted document.
Ensure you still have the original PDF file accessible, as you may need to reconvert the document using different settings to permanently resolve the formatting issue.
Use the Excel Open and Repair Tool
Use Microsoft Excel's built-in repair functionality to strip corrupted or excessive font formatting and force the file to open.
When a PDF is converted to Excel, the conversion tool often translates every minor text variation into a brand-new font style. This quickly exceeds Excel's maximum allowed unique cell formats.
The Open and Repair tool can often recover the data by discarding the excess formatting that triggers the limitation error.
Open Microsoft Excel first. Do not double-click the problematic file to open it directly.
Click on 'File' in the top left corner, select 'Open', and click 'Browse' to locate your converted Excel file.
Click once on the file to select it. Instead of clicking the main 'Open' button, click the small drop-down arrow next to the 'Open' button and choose 'Open and Repair...'.
When prompted, click 'Repair' to recover as much of your work as possible. If successful, immediately save the file under a new name.

Reconvert the PDF with Simpler Settings
Prevent the font limit error from occurring by adjusting your PDF to Excel converter settings before creating the file.
Open in a Newer Version of Excel
Older versions of Excel have stricter limits on unique cell formats. Upgrading or switching to a modern version can bypass the restriction.
Bypass Excel Limitations with WPS Office
If Microsoft Excel struggles to open your converted spreadsheets due to rigid font and formatting limitations, consider switching to WPS Office. It provides a lightweight, highly compatible alternative for viewing, editing, and managing complex spreadsheets without triggering legacy Office errors.

Frequently Asked Questions
What does the 'No more new fonts may be applied' error mean?
This error indicates that the Excel workbook has reached the maximum number of unique cell formats (combinations of font types, sizes, colors, and borders) allowed by your specific version of Microsoft Excel.
Why does this error happen specifically when converting from PDF?
PDF files use exact positioning and thousands of slight variations in text styling to maintain visual fidelity. When a conversion tool translates this to Excel, each tiny variation is often created as a brand-new custom font style, quickly maxing out Excel's built-in limits.
Can I increase the font limit in Microsoft Excel?
No, the maximum number of unique fonts and cell formats is hardcoded into the application framework. The only ways around it are clearing unnecessary formatting, reconverting the document without formatting, or using a modern spreadsheet alternative.
How can I remove excess formatting if the file refuses to open?
You can use Excel's 'Open and Repair' feature from the File menu to strip out corrupted or excessive formats during the opening process. Alternatively, opening the file in a different program like WPS Spreadsheet can bypass the specific Microsoft Excel restriction.
