XLSX to PDF

The standard Excel format since 2007 (.xlsx) to PDF. Your files are never uploaded to a server.

.xlsx · Free · No sign-up · No size limit

XLSX has been the standard Excel format since 2007. Send a spreadsheet as is and the other person may change formulas or see different column widths, but converting to PDF fixes it exactly as it prints. It is good for sending quotes and settlement sheets as a final version.

The moatool converter never uploads your document. A real office engine runs inside your browser to build the PDF, so even sensitive files stay on your device and there is no size limit.

How to convert XLSX to PDF

XLSX has been the Excel standard since 2007. Send a spreadsheet as is and the other person may change formulas or see different column widths, but converting to PDF fixes it exactly as it prints.

How to convert

Click Open converter above to open the office converter. The conversion engine (LibreOffice) gets ready once in the background the first time.
Drag a .xlsx file in, or pick it with Choose file. The file is not uploaded — it stays inside your browser.
Press Convert to PDF and it is built right on your device and saved. From the second time on, the engine is cached and starts instantly.

When to use it

Finalizing quotes and settlement sheetsSend a final version whose values will not change.

Tables for reportsAttach them to a document exactly as they print.

Hiding formulasKeep only the calculated results and hide the formulas.

Tip Tables with many columns can run past the page width and get cut. Set the print area and scale in Excel first, then convert, for a clean result.

Frequently asked questions

What happens with multiple sheets?

Each sheet goes into the PDF pages in order. If a print area is set, it follows that range.

Will wide tables get cut off?

Tables with many columns can run past the page width and get cut. Set the print area and scale in Excel first, then convert, for a clean result.

Is there a file size limit?

No. Because nothing is uploaded to a server there is no upload cap; the only limit is your device memory.

Why is the first run slow?

The office engine is downloaded once the first time. After that it starts right away — you are downloading the engine, not sending your document.

Does my file go to a server?

No. A real office engine runs inside your browser to make the PDF, so contracts and HR files stay on your device.
