Drop YAML (YML) 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 XLSX, or download everything as one ZIP if you converted several files.
The YAML to XLSX converter is part of this page and runs inside your browser. Your config files 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.
YAML's indentation rules are easy to break, and many APIs only accept JSON. XLSX opens straight into Excel with columns and data types intact. YAML is at home in configuration files written by people; XLSX is the usual choice for spreadsheets with formulas, formatting and several sheets.
A list of records becomes a table with one row per record. Nested keys turn into columns named like address.city, list items into columns like tags.0, and a key that only some records have leaves empty cells in the others. If the top level holds several lists of records, each becomes its own table, placed on its own sheet; a document that is a single object becomes one row.
YAML expresses the same structures as JSON using indentation instead of brackets, and allows comments. It is the usual choice for configuration in tools like Docker Compose, Kubernetes and GitHub Actions.

No. The YAML to XLSX 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 XLSX 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 YAML file, press Convert and save the XLSX. There is nothing to install.
Yes. Data files up to 300 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.
