JSON workspace
Paste JSON into the editor and use the actions below. All parsing and rewriting happens in your browser tab.
0 characters
Pretty print
?
Parses your JSON and rewrites it with indentation so it is easier to read. Everything stays in this tab—nothing is sent to a server.
Large payloads may feel slow; your browser is doing the work.
Minify
?
Removes whitespace between tokens to produce a compact single-line string—handy before caching or embedding in HTML.
Invalid JSON cannot be minified; fix parse errors first.
Validate
?
Runs JSON.parse locally to confirm the text is valid JSON. Your data never leaves the device.
This checks syntax only—not schema or business rules.
