Convert Excel file to PDF

Why convert your Excel files to PDF with ModySign?

Excel is a great working tool but a poor sharing format. Recipients may not have Excel installed, versions differ, and the slightest font change breaks the layout. PDF solves all of that in one step: recipients see exactly what you see, and the file opens anywhere (Windows, Mac, Linux, iOS, Android).

Most online Excel→PDF converters (Smallpdf, iLovePDF, PDF24) upload your spreadsheet to their foreign servers. For a cashflow tracker, payroll, GDPR client export, that's unacceptable. ModySign runs the conversion entirely in your browser thanks to SheetJS and pdf-lib — your data never leaves your machine.

Typical use cases: send a budget to a client without risking edits, archive a finance export, attach a planning to an email, share HR or sales reports with a third party. Known limitations: advanced formatting (conditional colors, charts) isn't preserved — the classic browser-side conversion trade-off, fine for 90% of business use.

Questions fréquentes

Are all sheets of my workbook converted?+

Yes. Every sheet becomes a dedicated section in the PDF, with its name as title. Empty sheets are skipped automatically.

Is my Excel uploaded to your servers?+

No, never. The conversion runs entirely in your browser via SheetJS and pdf-lib. Your data NEVER leaves your machine — unlike Smallpdf, iLovePDF or PDF24 which upload your files to their foreign servers.

Are colors, formulas and charts preserved?+

Cell values are preserved (including formula results). However colors, borders, charts and conditional formatting aren't rendered — the classic trade-off of a 100% browser conversion without a full Office engine. Fine for 90% of business use.

What formats are supported?+

Modern (.xlsx Excel 2007+) and legacy (.xls Excel 97-2003) are both supported. CSV files can be converted via our Text to PDF tool.
