Open a file, clean up its formatting, and see how the data fits together. You can follow these steps in airplane mode using the built-in example.
Open JSON
On Home, tap Example to try the app. Use Paste for clipboard text or Open file to select a local UTF-8 file. The plus button also opens the Android file picker. If a draft is open, confirm before replacing it.
Format or minify
Format JSON adds indentation and line breaks. Minify removes whitespace between tokens. Choose two spaces, four spaces, or a tab under Settings → Indentation.
