Your text stays in this browser and is not sent to Open Provinces. Clear it before leaving a shared device.

How to use the formatter

Paste a JSON document, then choose Format to add readable indentation or Minify to remove unnecessary whitespace. The tool checks syntax first and changes the text only when it is valid. Comments and trailing commas are not part of standard JSON syntax.

Copy puts the current text on your clipboard; Clear empties the field. Avoid pasting secrets or personal information into a shared device.
