These options help filter pasted JSON data safely while keeping enough context to understand why records matched or did not match.

Filtering JSON Arrays Without Writing a Script

JSON arrays from APIs, logs, exports, and test data often contain more records than you need. Filtering by a key, status, category, number, boolean flag, or nested path helps you quickly isolate the records that matter.

This tool filters an array of JSON objects locally in your browser. You can match text, numbers, booleans, missing fields, regex patterns, ranges, and nested dot paths before copying the filtered JSON or exporting a report.

When This JSON Array Filter Helps

Filtering API response records by status, category, owner, region, environment, feature flag, or error type.

Finding records where a field is missing, empty, truthy, falsy, above a number, or inside a range.

Creating a smaller JSON sample before converting it to CSV, Markdown, or a bug report.

Testing dot-path filters such as user.role, meta.source, or product.category before writing code.

How to Use the JSON Array Filter Tool

Paste a JSON array of objects into the input box.
Enter the key or dot path you want to filter by.
Select a condition such as equals, contains, greater than, between, missing, or regex.
Choose the output format and whether to keep matching or non-matching records.
Review the filter preview and copy the filtered output.

Example Filter

Filter key:
category

Condition:
equals

Value:
JSON & Data

Result:
Only records where category is "JSON & Data" are kept.

Filtering Is Best for Small and Medium JSON Samples

This browser tool is useful for pasted API responses, examples, exports, and moderate JSON samples. Very large datasets are better filtered in a database, command-line tool, or local script because browser previews can become hard to review at scale.

Frequently Asked Questions

What does this JSON array filter tool do?

It filters records in a JSON array by a selected key, value, comparison condition, and optional nested dot path.

Can I filter nested fields?

Yes. Enable flattening and use dot paths such as user.role, meta.source, or product.category.

Can I filter numbers and booleans?

Yes. Use the value type setting to compare text, numbers, booleans, or auto-detected values.

Can I find records where a key is missing?

Yes. Choose the Missing condition to find records that do not contain the selected key or dot path.

Is anything uploaded while filtering JSON?

No. The filtering runs entirely inside your browser.
