How to use Extract JSON Values
- 1. Paste your JSON. Paste the JSON object or array you want to inspect. The tool traverses every nested object and array, collecting each leaf value it finds along the way.
- 2. Set uniqueness and quoting. Turn on Unique values only to drop repeated values from the list, and Quote strings to wrap string values in quotes so they stay visually distinct from numbers and booleans in the output.
- 3. Copy the list of values. Copy the resulting list, one value per line, and use it to scan a document's actual data, build a lookup list, or spot duplicate or unexpected values quickly.
When to use Extract JSON Values
Extract JSON Values pulls out every leaf value from a JSON document, ignoring the keys and the nesting, and lists just the data itself. Reach for Extract JSON Values when you care about what values exist somewhere in a structure rather than where each one lives.
- Collecting all IDs referenced in a document. A large JSON payload references many IDs scattered across nested objects and arrays, and you want a flat list of every value to cross-check against a database.
- Checking for duplicate entries across records. You suspect the same value, like an email address, appears in more than one place in a dataset, and a unique values list makes duplicates obvious immediately.
- Building a dropdown or autocomplete list. You want to populate a select input with every distinct value that has appeared in a field across a JSON dataset, without writing a script to walk the structure.
- Reviewing what data a payload actually contains. Before deciding how to process a JSON file, you want a quick sense of the range of values inside it, separate from the structure that holds them.
Examples

About the Extract JSON Values tool
Extract JSON Values runs as plain JavaScript in your browser tab, with no server behind it. Extract all values from objects in JSON data. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's JSON Tools section, 90 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Unique values only and Quote strings, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Extract JSON Values cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
