Frequently asked questions

Yes. Formatting, minifying, validation, tree view, and the local library work on your Android device. Android may also show cloud locations in its file picker. Choose a file already available on your device when you are offline.

Formatting adds whitespace and indentation for readability. Minifying removes whitespace between JSON tokens for a more compact result. Both preserve the values and the whitespace inside quoted strings.

Home shows an explanation with a line and column. Tap the message to move the cursor. Check that object keys and strings use double quotes, and remove trailing commas before closing braces or brackets.

Save keeps a copy inside the app’s Library. Export makes a separate file in the location you choose through Android’s picker. Export important files before clearing app storage or uninstalling.

The app accepts UTF-8 JSON of up to 2 MiB with up to 128 levels of nesting. JSON objects, arrays, and scalar values are supported. If formatted output would exceed the limit, use fewer spaces or Minify.

The app processes your documents locally and does not upload them to the developer. Copy and Export give data to the Android clipboard or the file destination you deliberately choose.
