What does this tool do?
Filter a JSON array of objects down to the items matching one simple condition. Everything runs locally using JavaScript in your browser — nothing you paste or upload is ever sent to a server.
How to use this tool
- Paste your json array into the left-hand box.
- Fill in the condition field above the input.
- Click Filter JSON.
- Copy the filtered json from the output box.
Frequently asked questions
What operators are supported?
==, !=, >, <, >=, <= for comparisons, and contains for a case-insensitive substring match on text.
Can I use nested keys in the condition?
Yes, use dot notation such as address.city == "NYC" to filter on a nested field.
I need to combine multiple conditions with AND/OR — is that possible here?
This tool supports exactly one condition. For AND/OR chains across multiple conditions, use the JSON Query Tool instead.
