Question details
Users experience prolonged wait times when converting Excel workbooks to PDF, accompanied by formulas temporarily disappearing from the spreadsheet.

- Product
- Adobe Acrobat PDFMaker and Microsoft Excel
- Device & OS
- Windows
- Scenario
- Converting an Excel workbook to a PDF document using the Adobe PDFMaker add-in integrated within Microsoft Excel.
- Observed behavior
- The conversion process takes several minutes to complete, and Excel formulas may appear to vanish from the workbook until the Excel application is restarted.
Ensure you have saved your current Excel workbook, closed any background applications, and noted your Adobe Acrobat login credentials in case a reinstallation is required.
Remove Unavailable Printers and Disable Acrobat Online Storage
Clearing inaccessible networked printers and preventing Acrobat from pinging online storage can resolve background hanging issues.
Acrobat PDFMaker can sometimes hang when the system attempts to verify installed but inaccessible networked printers, or when Acrobat is constantly checking online storage connections.
Navigate to your Windows Settings, go to 'Devices', select 'Printers & scanners', and remove any printers that are no longer accessible or connected to your network.
Open Adobe Acrobat, go to 'Edit' > 'Preferences' > 'General', and uncheck both 'Show online storage' options, then click 'OK'.
Test Windows User Profile and Excel Add-ins
Determine if the slow conversion is restricted to a damaged user profile or caused by conflicting third-party Excel add-ins.
Clean Reinstall Adobe Acrobat and Microsoft Office
If system configuration changes do not work, a clean installation of Acrobat and Office can resolve deep registry and file corruption issues.

Frequently Asked Questions
Why does Excel PDFMaker take so long to convert files?
Slow performance is often caused by conflicting third-party Excel add-ins, inaccessible networked printers causing the system to hang, or Acrobat attempting to verify online storage connections in the background.
Will reinstalling Acrobat fix missing Excel formulas during conversion?
Yes. If formulas disappear during conversion, the issue usually stems from deep corruption in the PDFMaker add-in or the Microsoft Office integration. Reinstalling Adobe Acrobat or repairing Microsoft Office generally resolves this.
How do I remove Adobe Acrobat completely before reinstalling?
For standalone Acrobat installations, you should uninstall the program via Windows Settings and then run the official Adobe Acrobat Cleaner tool. This removes all residual traces and registry entries before you perform a fresh installation.
Can I convert Excel to PDF without using Adobe PDFMaker?
Absolutely. You can use Microsoft Excel's built-in 'Save As PDF' feature, or use alternative office suites like WPS Office, which include a dedicated, lightning-fast PDF export tool natively without requiring add-ins.
