About this tool

Raw JSON is hard to scan. This viewer renders arrays and objects as sortable, readable tables so you can explore API payloads and config files visually.

Paste minified or pretty JSON to collapse nested structures into rows and columns without writing ad-hoc scripts.

Common use cases

  • Inspecting API responses during integration
  • Reviewing analytics or log exports in tabular form
  • Sharing structured samples with non-developers
  • Validating array length and field presence quickly

How to use

  1. Paste JSON into the input editor.
  2. Wait for the table view to render from detected array data.
  3. Scroll and scan columns for anomalies or missing fields.
  4. Copy formatted output or switch views if the tool supports raw JSON.

Understanding the result

  • Arrays of objects render as one row per element with keys as columns.
  • Deeply nested objects may appear as expandable cells or flattened paths.
  • Invalid JSON shows a parse error—fix syntax before a table appears.
  • Very wide objects produce many columns; filter in source JSON if needed.

FAQ

What JSON structures work best?

Uniform arrays of objects tabulate cleanly. Mixed types may produce sparse or uneven columns.

Can I sort columns?

If sorting is enabled, click column headers to order rows for quick scanning.

Does it validate JSON?

Parsing errors are reported. Valid JSON is required before table rendering.

Is my JSON sent to a server?

No. Rendering runs entirely in your browser.
