JSON Table Viewer

Click any column header to sort that column ascending. Click again to sort descending. The tool detects data types automatically — numeric columns sort numerically (10 comes after 9, not between 1 and 2), date-like strings sort chronologically, and other strings sort alphabetically. A third click clears the sort and restores the original order.

Yes. The search box filters all rows in real time — it matches any cell value in any column. Search is case-insensitive. For example, typing "london" hides all rows where no cell contains that string. Pagination updates alongside the filter so you always see the count of matching rows. There is no column-specific filter, but you can sort a column first to group similar values before searching.

Objects nested inside the array items are flattened using dot notation: {"user":{"name":"Alice","city":"NYC"}} becomes two columns — user.name and user.city. Arrays nested inside items are displayed as a compact JSON string in a single cell. The tool shows a "Nested objects detected" notice when flattening occurs so you know the table structure has been modified from the original JSON.

Click Download CSV to export the current table view — including any active search filter or sort order. The CSV uses comma separators with double-quote encapsulation for values that contain commas or newlines. Column headers in the CSV match the table column names (including dot-notation keys for flattened objects). Open the exported file directly in Excel, Google Sheets, or any spreadsheet app.

File uploads accept up to 10 MB. Pasted data has no hard limit, but datasets over 10,000 rows may slow rendering in older browsers. Pagination helps manage large datasets — set rows per page to 25, 50, or 100, or choose Show All. For very large JSON files (100k+ records), consider splitting the data before pasting.

Yes — that is the most common use case. Copy a JSON response from Postman, cURL, or your browser's DevTools network tab and paste it directly. If the response is a single object rather than an array, the tool wraps it in an array automatically so it renders as a one-row table. Arrays nested inside the response at the root level are detected and used as the data source.

No. Everything is processed in your browser with JavaScript — zero server calls, zero uploads. You can safely paste internal API responses, database exports, or any sensitive JSON data.
