JSON Filter Tool – Filter JSON Arrays Online
Filter JSON arrays based on conditions like equals, contains, and range. Our free JSON Filter Tool lets you extract exactly the data you need without writing any code.
About JSON Filter Tool
Filtering JSON arrays manually means writing code for every different condition. This tool lets you filter arrays using a simple UI with conditions like equals, contains, greater than, and more, no coding required.
How it works
Paste a JSON array, enter the key path to filter on (like "city" or "user.age"), select a condition, and enter the compare value. Click Filter to see matching items.
Supported conditions include equals, contains, greater than, less than, starts with, and ends with. The filtered result shows the count and full JSON of matching items.
When you'd use this
You have a list of users, products, or records and need to find items matching specific criteria. Filter here to get just the subset you need for testing or analysis.
This filters at one level using a single condition. For complex multi-condition filtering or nested property filtering, you'd need to write custom code.
Questions
What kind of input does this accept?
Only JSON arrays at the root level. Objects or other types will show an error. Wrap your data in [] if needed.
How do I filter nested properties?
Use dot notation like "user.profile.city" to access nested values. Each dot moves one level deeper into the object.
Can I use multiple conditions?
No, this tool applies one condition at a time. For multiple conditions, run filters sequentially or use a more advanced tool.
Does greater than work with strings?
Greater than and less than compare numerically. Non-numeric values won't match these conditions correctly.
How do I get the filtered data?
Use Copy to paste into your code or Download to save as a JSON file. Both options appear after filtering.
