JSON Pretty Print
Make compact JSON easier to read with consistent indentation and line breaks. Choose two spaces, four spaces, or tabs, then copy the beautified JSON.

Beautify JSON for reviews, examples, and debugging
Pretty printing adds a readable layout to compact JSON. Nested objects and arrays receive indentation so their structure is easier to follow in an API response, a bug report, or a code review. JSON beautifier and JSON pretty printer describe the same operation here: validate the input, then serialize it with the indentation you choose.
How to pretty print JSON
- Paste compact or unevenly formatted JSON.
- Choose two spaces, four spaces, or tabs from the indentation control.
- Select Pretty Print JSON and copy the formatted text.
JSON Pretty Print example
{"team":"support","members":["Alex","Sam"],"active":true}Choose four spaces for a wider nested layout, or two spaces for a more compact readable result. Tabs are also available.
Syntax checks and data representation
The tool uses JavaScript JSON parsing. Syntax validation does not check a schema or application rules. Formatting and minification parse and serialize the document: duplicate property names collapse to the last value, integer-like keys may reorder, and numbers beyond JavaScript’s safe integer range can lose precision. Keep long numeric identifiers as strings and retain your original source when exact representation matters.
JSON Pretty Print questions
Is pretty printing the same as beautifying JSON?
Yes. In this tool, both mean adding consistent indentation and line breaks to valid JSON. They do not repair invalid syntax.
Can I choose the indentation width?
Yes. Choose two spaces, four spaces, or tabs before selecting Pretty Print JSON. You can change the selection and format again.
Does pretty printing sort object keys?
No alphabetical sort is applied. The tool uses JavaScript parsing and serialization, which can reorder integer-like property names and normalize number or escape representations.
