Hand over your workbook as PDF pages that open without Excel and show the results, not the formulas behind them.
Converting XLSX to PDF turns a live workbook into fixed pages that anyone can open without Excel and nobody can accidentally change. Every formula is replaced by the value it displayed, and the sheet is cut into pages according to the workbook's own print settings, so a wide sheet may split across several pages.
Transfers use HTTPS, and files converted on the free tier are deleted within 24 hours, so the result is not a long-term archive. Quality depends on the source file, so open the PDF file once before you share it.

XLSX (Office Open XML Workbook)
The Excel workbook format introduced with Office 2007, built on Office Open XML. One file holds any number of worksheets, each a grid of cells with values, formulas, number formats and styling, plus charts, pivot tables and print settings.
PDF (Portable Document Format)
A paginated, fixed-layout format (ISO 32000) designed so a document prints the same everywhere. It has pages of a set size and no concept of cells, rows or formulas, only text and lines drawn at fixed positions.

Each cell appears as it was displayed, with its number format and rounding, and no calculation behind it. A client reading an invoice or quote sees the totals and cannot alter the figures or read the formulas.
The print area, paper size, orientation and scaling saved in the XLSX decide which columns and rows land on each page. Set them in Excel before you upload, because they travel inside the file.
Spreadsheets are awkward to read on a small screen, while a PDF opens directly. Download the result or send a share link to whoever needs the numbers; converting one workbook takes no account and no install.
Set the print area, orientation and scaling in Excel and save. The saved workbook can then be chosen from your device or imported from Dropbox or Google Drive.
Start the conversion once PDF shows as the output format. If you realise you added the version with the wrong print area, cancel the job while the progress bar is still running.
Check for columns pushed onto extra pages, cells printed as hash signs and sheets you did not expect. Adjust the print settings in Excel and convert again if needed.
You get a paginated PDF, typically with each visible sheet in order, and with text that normally stays selectable and searchable in a PDF reader. Hidden rows, columns and sheets are normally left out, and sorting, filtering and pivot tables stop working because only the visible result is kept. The workbook is converted on indox infrastructure, not in your copy of Excel, so fonts, column widths or page breaks can differ slightly from Excel's own print preview.
The upload box shows the live size limit before you add a file. Signing in raises it, and paid plans raise it further.
XLSX in, PDF out. Pick another output on the converter if you need a different format.

| What you see | Why | What to do |
|---|---|---|
| Columns spill onto extra pages | The sheet is wider than a page, so the converter splits it | Set the orientation and the scale to fit in the workbook's page layout, then convert again |
| The formulas are gone | A PDF holds formatted pages, and the formulas stay in the XLSX | Share the PDF and keep the XLSX as the file you work in |
| I need the numbers as data | A PDF page is for reading, not for processing | Use XLSX to CSV to get the values as plain text |
| Compared on | XLSX | |
|---|---|---|
| What it is | A workbook of one or more worksheets (ISO 29500) | A format for formatted, page-oriented documents (ISO 32000-1) |
| Layout | A rectangular grid of cells | Pages |
| Formulas | A cell can hold a value or a formula, usually with a cached value | No formulas; the page holds formatted content |
| Role | A container for data, and for formulas that analyse it | Generally a final-state format for delivery to end users |

No tool matches that search.
Set it in the workbook before converting. In Excel, open Page Layout and under Scale to Fit choose 1 page wide (and 1 page tall if needed), or switch the orientation to landscape. That scaling is stored inside the XLSX file and is what determines the page breaks. Very large sheets become too small to read.
No, only their results. A PDF has no calculation engine, so each formula cell is written out as the number or text it was showing, formatted the way the cell was formatted. Anyone reading the PDF cannot see how a total was calculated. Keep the XLSX file if the working needs to stay available.
The sheet is wider or longer than the paper size set in the workbook. Spreadsheet printing fills a page with as many columns as fit, then continues with the remaining columns on later pages. Narrower margins, landscape orientation, a smaller scale or a defined print area in the source file all reduce the splitting.
Typically every visible worksheet is printed, one after another in tab order, and hidden sheets are skipped. This varies between converters and can also be affected by print areas defined on individual sheets. If you need only one sheet in the PDF, the dependable method is to save a copy of the workbook that contains just that sheet.
You can, but expect to tidy the result. The PDF stores text at positions on a page, not cells, so rows and columns have to be guessed from the alignment, and formulas are gone for good. Numbers may come back as text. Treat the PDF as a copy for reading and keep the original workbook.
Normally they will not. Printing follows what is visible on the sheet, so anything hidden or filtered out is omitted from the pages. That is convenient for layout, but it is not a security measure for the source file: the hidden data is still inside the XLSX if you send that as well.
