Tool
JSON Formatter
Turn messy JSON into readable text, or squeeze it into one line.
Paste JSON on the left, then format or minify.
How to use
Paste JSON into the input, then Format to indent it or Minify to compact it. Copy the result in one click.
FAQ
- Is my data uploaded?
- No. Formatting runs locally in the browser. The page does not send JSON to a server.
- Why does parsing fail?
- The input is not valid JSON. Trailing commas, single quotes, or unquoted keys are common causes.
- What is the difference between Format and Minify?
- Format adds indentation for reading. Minify strips whitespace for pasting into configs or payloads.
