    The details

    What happens when you convert a spreadsheet to PDF

    The original binary Excel workbook, from before 2007. The sheet is laid out page by page, with the column widths and row heights preserved, and the result is written out as a fixed-layout PDF. The result is a the portable document format. fixed layout, universal, and the reason everyone can open the file you send them, produced entirely inside your browser.

    What survives

    • The numbers, exactly as calculated
    • The column order and the row order
    • Cell formatting, including number formats and fills

    What changes

    • The formulas — only their current values are printed
    • Anything beyond the printed area, such as hidden columns

    Where it goes wrong

    • A sheet wider than the page is split across pages, and the column headers may not repeat
    • Charts and pivot tables often land on separate pages from their data
    • Very wide sheets are far more readable as CSV than as PDF

    Why anyone would do this

    A PDF of a table can be read, printed and filed. A spreadsheet can only be opened by a spreadsheet.

    About the format

    The original binary Excel workbook, from before 2007.

    A binary compound file with a stream per worksheet and a shared formatting table.

    Where it is good
    • Opens in absolutely every version of Excel ever shipped
    • The reference format for very old reporting systems
    • Sometimes opens files that the modern format refuses
    Where it falls short
    • Row limit of 65,536 — a real constraint on data
    • Larger than XLSX for the same content
    • No modern features like dynamic arrays or rich charts
    You will find it on
    Legacy ERPs, old Excel installs, some government portals

    The thing people miss

    If a spreadsheet will not open in modern Excel, converting it to .xlsx and back is often enough to fix it.

    About the target

    The portable document format.

    A tree of objects describing pages, fonts, images and scripts, with a cross-reference table and a file trailer. Text and vector graphics are stored separately from the page layout.

    • Looks identical on every operating system and every device
    • Holds text, images, vector art, forms, signatures and 3D
    • Can be locked, compressed, tagged for accessibility and archived as PDF/A

    Questions

    XLS conversion questions

    What actually happens to my XLS file when I convert it to PDF?

    The sheet is laid out page by page, with the column widths and row heights preserved, and the result is written out as a fixed-layout PDF. So the XLS file is unpacked, the content is laid out, and the result is written out as PDF. The numbers, exactly as calculated survives unchanged.

    Will converting XLS to PDF reduce the quality?

    For this particular conversion, not in the way you would expect. The numbers, exactly as calculated — the XLS content is not re-encoded in a lossy way. The only thing that changes is the format it is stored in.

    Is my XLS file uploaded to a server?

    No. This XLS to PDF conversion runs as JavaScript inside your browser tab. The file is read from your device and the result is written back to your device, so there is no upload step, no file-size limit and no copy of your XLS file on any server.

    Do I need an account or will there be a watermark?

    Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.

    What is the most common mistake people make when converting XLS to PDF?

    A sheet wider than the page is split across pages, and the column headers may not repeat

    Why would somebody convert XLS to PDF at all?

    A PDF of a table can be read, printed and filed. A spreadsheet can only be opened by a spreadsheet. In short: opening a spreadsheet from an old system
