Swap JSON Keys with Values reverses keys and values in a flat JSON object. The Swap JSON Keys with Values tool supports live preview, file upload, copy, and export.
How to Use:
Paste a flat JSON object into the Input JSON box. You can also import a .json or .txt file using the Choose File button. Once your input is valid, the Swap JSON Keys with Values tool immediately inverts each key-value pair and displays the result in the Swapped Output box.
The tool only works with simple, one-level JSON objects where values are strings or numbers. Arrays, nested objects, and nulls will trigger an error. When changes are made, the output flashes and updates in real time. A character counter below the output shows the result length.
Click Copy Output to copy the swapped JSON to your clipboard. You can also export it as a file with Export to File. Use Clear All to remove everything and start over.
What Swap JSON Keys with Values can do:
This tool helps you flip the structure of a flat JSON object turning values into keys and keys into values. It’s especially useful for reversing lookup tables, creating reverse maps, or inverting label-based data. It works directly in your browser, with no need for setup or external tools.
Example:
Input:
{ "a": "x", "b": "y", "c": "z" }Output:
{ "x": "a", "y": "b", "z": "c" }Common Use Cases:
Swap JSON Keys with Values is great for converting mapping data, flipping name-value pairs, or transforming JSON before reuse. Developers often use it to reverse lookup maps, reformat config data, or debug inverse relationships in JSON sources.
Useful Tools & Suggestions:
Before swapping, Extract JSON Keys can help you see exactly what you’re working with. And after the flip, Analyze JSON makes it easier to understand how the structure’s changed and whether the new format still holds up.
