Find the perfect JSON editor for your needs. Whether you prefer online tools or desktop applications, we've got you covered.

Online JSON Editors

JSON Formatter & Editor

JSON Formatter from jsonformatter.org provides excellent JSON editing functionality. You can type your JSON in the edit box on the left and it will be formatted with proper indentation and line feeds. You can also click on the "Compact" icon in the edit box menu bar to transform your JSON to compact/minified format.

This JSON editor also provides a quite useful feature of collapsing parts of JSON while still being in editing mode. This could be quite helpful when working on a complex JSON file with multiple nesting levels. To collapse part of JSON click an arrow next to the line number. To expand collapsed JSON click on the same arrow next to the line number or click on the "expand" icon which will be displayed instead of the collapsed text.

Besides editing, JSON formatter also provides multiple additional features:

  • Click on the "JSON Graph" icon to display JSON in a graph format
  • Use the "filter" icon to execute queries in JMESPath format
  • Sort your JSON by clicking on the "Sort" button
  • View JSON as code, form, text, tree, or visual representation
