How to use JSON Viewer
Paste JSON, then format, validate and inspect the nested structure. Correct any reported syntax position before copying the result.
What the tool does
Paste JSON to format and inspect its structure, identify syntax problems and work with readable data in your browser.
Supported inputs
The code, JSON, expression or encoded text requested by the editor, using a fabricated or redacted sample rather than a live secret.
Actual output
An interactive result or saved workspace with only the actions relevant to its current state.
Privacy and processing
Processing runs locally unless the tool clearly requests a public network resource.
Limitations
Very large JSON documents can use substantial browser memory. Comments and trailing commas are not valid standard JSON.
Common mistakes
Check that the selected input type, units and output format match the task. Do not discard the source before opening the result, and do not treat a preview, estimate or converted file as verified until you have reviewed it.
