Excel files are interactive and editable — which is great for internal work, but not ideal when sharing with clients, stakeholders, or the public. Converting to PDF locks in the formatting and prevents accidental changes, formula exposure, or hidden-sheet leaks.
A PDF version of your spreadsheet is also universally readable without Microsoft Excel or any spreadsheet software. It renders identically on every device and platform.
.XLS is the legacy binary format from Microsoft Excel 97–2003. .XLSX is the modern Office Open XML format introduced with Excel 2007. Both are fully supported by OneClickPDF via LibreOffice Calc.
XLSX files are generally smaller, faster to process, and more reliably converted. If you have an older .XLS file and experience conversion issues, re-saving it as .XLSX in Excel or Google Sheets before uploading may improve fidelity.
No. Conversion happens entirely on the server using LibreOffice Calc. No Excel, no Office 365, no software installation required.
Computed formula values, cell formatting, borders, colors, and fonts are preserved. Macros, VBA scripts, and interactive controls are not functional in the PDF output — only the visual result is included.
Yes. All sheets in the workbook are converted. Each sheet is included in the PDF as one or more pages depending on its print area and page layout settings.
The maximum upload size is 10 MB. Most spreadsheets are well under this limit.
No. Files are processed in memory and deleted immediately after conversion. Your spreadsheet data is never stored or logged on our servers.
