How to Fix Letter Spacing Changes When Exporting Excel to PDF
Question details
The user is experiencing changes in letter spacing and font rendering when exporting an Excel worksheet to a PDF file.

- Product
- Microsoft Excel
- Device & OS
- macOS
- Scenario
- Saving or exporting a finished Excel spreadsheet as a PDF document for sharing or printing.
- Observed behavior
- The text formatting, specifically letter spacing and font layout, changes unexpectedly in the exported PDF compared to how it originally looked in Excel.
Ensure your macOS and Microsoft Office applications are updated to their latest versions, as printing and rendering engines frequently receive bug fixes. Verify that the specific fonts used in your spreadsheet are actively enabled on your operating system.
Verify and Install Missing Fonts Locally
Missing fonts trigger font substitution during PDF conversion, which alters letter spacing. Installing the exact fonts ensures accurate layout rendering.
Excel relies on system fonts to generate PDFs. If a custom or third-party font used in the spreadsheet is not installed on the current device, Excel will substitute it with a standard font, causing spacing irregularities.
Open your Excel file, click on the cells with the spacing issues, and note the exact font name displayed in the Home tab's font dropdown.
On your Mac, open the Font Book application and use the search bar to check if those specific fonts are installed.
If the font is missing, download the font file (.ttf or .otf), double-click to install it via Font Book, then restart Excel and export the file to PDF again.

Use a Dedicated PDF Conversion Tool
A professional PDF converter often handles font embedding and rendering better than Excel's native export feature.
Export the Worksheet as an Image
Bypass text rendering differences entirely by converting the problematic cell ranges into a static image format before creating the PDF.
Convert Spreadsheets to PDF Accurately with WPS Office
WPS Office offers a built-in PDF converter that accurately preserves cell layouts, precise letter spacing, and custom fonts from your spreadsheets, bypassing the rendering issues often found in other applications.
- 1. Open your spreadsheet: Launch WPS Office and open your .xlsx or .xls file.
- 2. Access the PDF export tool: Go to the 'Menu' or 'Tools' tab and click on the 'Export to PDF' button.
- 3. Configure export settings: Select the sheets or print area you wish to convert and verify your layout preferences.
- 4. Save as PDF: Click 'Export' to generate a highly accurate PDF document with perfect text formatting.

Frequently Asked Questions
Why does my text look squished or overlapped when saving Excel as a PDF?
This typically happens because Excel's print rendering engine handles letter spacing differently than the screen display. If a font isn't properly supported or embedded during the PDF generation, the letter spacing can compress. Ensuring all fonts are locally installed usually fixes this.
Can I embed fonts in my Excel file before exporting to PDF on Mac?
Unlike Excel for Windows, Excel for Mac does not natively support embedding fonts directly into the workbook file. You must ensure the required fonts are installed in your macOS Font Book or use a dedicated conversion tool that handles external fonts better.
Will adjusting print scaling help fix PDF layout changes?
Yes, sometimes adjusting the print scaling helps. Go to Page Layout > Page Setup, and set scaling to 'Fit to 1 page wide'. This forces the print engine to recalculate cell sizes, which may indirectly resolve text spacing and cutoff issues in the exported PDF.
