Readability
Make API payloads easier to read
Pretty printing JSON is useful when reviewing logs, API responses, fixture files, or copied payloads that arrive as a single compressed line.
JSON Formatter
Pretty print or compact JSON in one place
Json VW works as a JSON formatter for developers who need cleaner payloads quickly. You can prettify minified JSON for review or compact formatted JSON to remove spaces before sharing or testing.
Compact Mode
Remove unnecessary spacing quickly
The compact action removes extra whitespace while preserving valid JSON structure, which is useful for copy-paste workflows, testing, and payload snapshots.
JSON Formatter FAQ
What is a JSON formatter?
A JSON formatter rewrites valid JSON into a cleaner layout, usually with indentation and line breaks, so the data is easier to read and debug.
Can I compact JSON too?
Yes. Json VW supports both pretty printing and compacting so you can switch between readable and minimal JSON text.
Does formatting change the data?
No. Formatting changes the layout of valid JSON text, not the underlying values or structure.
