JSON table viewer
A QUICK WALKTHROUGH
How to use this tool
- Paste a JSON array of plain objects.
- View the union of columns in first-seen order.
- Click a column heading to sort.
Accepted input
The input must be a JSON array whose entries are plain objects. Input is limited to 100,000 characters.
Columns and nested values
Columns use first-seen key order across rows. Missing values are blank; nested objects and arrays are rendered as compact JSON strings.
Safe local table
Cell values are assigned with textContent, so input cannot inject HTML. Column headings provide simple type-aware numeric and text sorting.
