JSON is the data format of the web: objects, lists, text and numbers in plain text. APIs, apps and settings files use it everywhere.
Extensions: .json

Drop on YAML
Release the files over YAML. A progress ring counts up, and each YAML file is saved next to its original.
What Filee does for JSON → YAML
YAML is easier to read and edit by hand, which is why config files use it. Keys keep their order, and text that would read back as a number or true/false is quoted.
- Built in: works right after installing Filee, with nothing else to download.
- Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
- Private: files are converted on your PC and never uploaded, even without internet.
- Saved next to the original, or in a folder and with a file name pattern you choose.
JSON can also become
- JSON Lines
- TOML
- XML
- CSV
- XLSX
