Formatted for readability
If you are working with API payloads or encoded data, you may also want to try our JSON tools or our encoding tools.
Related tools
  • Estimate LLM tokens to estimate the size and cost of JSON used in prompts, payloads or AI workflows.
  • Encode and decode Base64 to encode or decode payloads and strings used in API integrations.
  • Decode JWT to inspect header and payload when your JSON comes from a token.
  • Generate UUIDs to create unique identifiers for IDs used inside JSON fixtures and payloads.
  • Test a regular expression to validate or extract string values found inside JSON fields.
How it works
Format, validate and minify JSON directly in your browser. Paste raw JSON, make it readable, catch parsing errors and copy the result without sending data to external servers.
Practical examples
Format a JSON API response
Paste raw JSON returned by an API to make it readable, inspect nested objects and arrays, and copy the formatted output.
