JSON Filter Tool

A simple, responsive web-based JSON filter and converter. Import JSON, choose which keys to keep, preview results, and export into different JSON formats.

Auto-detects format (Map, List, List, List, Raw JSON).

Select which keys you want to keep.

Preview shows first value per key to keep it clean.

Export JSON in multiple structures:

Raw JSON → unchanged but filtered.

Map → single object.

List → array of objects.

List → array of strings.
