About YAML files

YAML is a readable config-file format used by many developer tools. Other tools only accept JSON.

How to convert YAML to JSON

  1. Drop your YAML on the box above, or click it to choose it.
  2. Click “→ JSON”.
  3. Your file downloads. MunchFiles checks that the result opens correctly before it hands it to you.

What to expect

Same data, in the format every tool reads.

Questions

Are my files uploaded anywhere?

No. MunchFiles converts files inside your web browser, on your own device. The file is never sent to a server, so nobody else can see it.

Is it free?

Yes. Basic file conversions are free, with no account and no watermark. MunchFiles Pro is an optional one-time purchase (no subscription) that keeps a copy of MunchFiles on your device, working offline, with power tools for batches, shrinking images and PDF pages.

Does it work on my phone?

Yes. It works in any modern browser on a phone, tablet or computer. There is nothing to install.

What if my YAML has several documents?

JSON holds one document, so MunchFiles tells you instead of picking one or merging them.

How big can the file be?

There’s no upload limit, because nothing is uploaded. Very large files are limited only by your device’s memory.
