Frequently asked questions
Can I download the sample without JavaScript?
Yes. The sample XLSX download is an ordinary file link on this page.
Can I change the sample and save it?
Yes. Open the sample in the editor, make supported edits and save an XLSX copy.
Is my workbook uploaded to a server?
The anonymous browser file tools process workbook contents locally. The website still makes ordinary requests for pages and sample files. Read the privacy page for details.

Choose XLSX files with a combined size of 128 MiB or less. Legacy XLS files and password-protected or encrypted workbooks are not supported.
