Drop XLSX (Excel) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the YAML, or download everything as one ZIP if you converted several files.
The XLSX to YAML converter is part of this page and runs inside your browser. Your spreadsheets are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
XLSX is awkward for scripts, databases and import tools that expect plain text. YAML is easier for people to read and edit than JSON and allows comments. XLSX is at home in spreadsheets with formulas, formatting and several sheets; YAML is the usual choice for configuration files written by people.
The first row is read as column names, and every row after it becomes one list item, keyed by those names. A header such as address.city is turned back into a nested address with a city. A workbook with a single sheet becomes a plain list; one with several sheets becomes an object keyed by sheet name.
XLSX is Excel's format since Office 2007. A workbook can hold many sheets with formulas, formatting and charts. Programs and scripts usually prefer the same data as CSV or JSON.

No. The XLSX to YAML conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The values are kept. Anything YAML has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the XLSX file, press Convert and save the YAML. There is nothing to install.
Yes. Spreadsheet files up to 150 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
