Excel to PDF Converter

Convert .xlsx spreadsheets to PDF in your browser. Renders each sheet as a styled table with header row, alternating rows, and choice of orientation.

PDF Tools

Cell values and the first-row header are rendered. Formulas show their evaluated results. Charts, conditional formatting, and cell colors are not preserved - for those, use Excel's File → Save As PDF.

About the Excel to PDF Converter

The Excel to PDF Converter renders each sheet of a .xlsx workbook as a clean table PDF. Cell values are extracted, the first row is styled as a header, alternating row backgrounds make wide tables readable, and the document paginates automatically.

Conversion uses SheetJS, the leading JavaScript library for reading Office spreadsheets. Everything runs in your browser - your file never leaves your device. Useful for sharing data extracts with people who cannot or will not open Excel files, or for printing data in a format that does not change between Office versions.

Common use cases

  • Send a data report to a non-technical stakeholder
  • Print pricing sheets, inventory lists, or contact directories
  • Archive spreadsheet snapshots that should not be editable
  • Convert exports from analytics tools or databases into shareable PDFs

Tips for best results

For best results, use simple tabular data with the first row as headers. Charts, conditional formatting, formulas-rendered-as-results (the actual evaluated values come through, not the formulas), and merged cells render as plain values. If your workbook has multiple sheets, only the first active sheet is rendered to PDF - to convert all sheets, save each as its own .xlsx first. Landscape orientation is recommended for tables with many columns.

Privacy & data handling

The Excel to PDF Converter runs entirely in your browser. The .docx or .xlsx file you upload is parsed locally on your device - nothing is uploaded, logged, or shared with any server. Files are released from memory the moment you close the tab. No signup, no daily limit, no watermarks.

What does the converter preserve?
Cell values across all visible cells, the order of rows and columns, basic number formatting (integers, decimals, dates as displayed). The first row is styled distinctly as a header.
What gets lost?
Charts, conditional formatting, cell colors, font colors, merged cells (rendered as single cells with first-cell content), formulas (only the evaluated result is kept), pivot tables, frozen panes, and protected sheets. If you need any of these in PDF, use Excel's built-in File → Save As → PDF.
How many sheets are converted?
The first visible sheet only, currently. To convert multiple sheets, save them as separate .xlsx files first (right-click sheet tab → Move or Copy → New book → Save).
Can I convert .xls (old Excel)?
Yes - SheetJS supports the older binary .xls format too. Just upload the file as you would .xlsx. For very old files (Excel 95 and earlier) the support is limited; save as .xlsx in modern Excel first.
Is my data safe?
Yes. The .xlsx parser runs in your browser, not on a server. We never see your data, log it, or store it. Particularly important for sales spreadsheets, customer lists, payroll, and other sensitive business data.
