About jq Playground

jq Playground runs jq filters against your JSON in the browser, so you can build and debug a jq command before you paste it into a shell script, a GitHub Actions step or a curl pipeline. The interpreter follows jq 1.7.1: the same builtins, regex and date functions, error messages and output format, with the -r, -c, -s, -n, -R and -S options.

Key Features

Full jq language: pipes, select, map, reduce, foreach, path expressions, def, try/catch and label/break
Loads jq 1.7.1's own builtin definitions, so group_by, paths, sub, gsub, limit and walk match the CLI
Prints numbers like jq does, keeping literals such as 19.90 and 12345678901234567890 exactly as written
Live mode re-runs as you type; Copy command gives you the matching jq line for your terminal
Reads JSON Lines and raw text input the way jq reads stdin, and supports input and inputs
Runs entirely in your browser, so API keys and customer data in the JSON never leave your machine

Use Cases

Pull instance IDs out of aws ec2 describe-instances output before a us-east-1 cleanup script runs
Flatten a Stripe or GitHub API response into CSV rows with @csv for a spreadsheet
Count pods by status from kubectl get pods -o json without opening a cluster dashboard
Write the jq step that reads a version from package.json in a GitHub Actions workflow
Check a jq one-liner from a blog post or Stack Overflow before running it on production logs
Teach a teammate jq by stepping through select, map and group_by on real data

Supported Formats

jq select example

Why does my jq filter work here but fail in my terminal?

Almost always it is shell quoting. In bash and zsh, wrap the whole filter in single quotes so the shell does not expand $variables or treat | and > as its own operators; if the filter itself contains a single quote, close the quote, add \', and reopen it. PowerShell and Windows cmd quote differently, so the Copy command button writes the bash form. Two other differences: env and $ENV are empty in a browser, and input_filename returns null because there is no file on disk.

Privacy & Security

All processing happens locally in your browser. Your data never leaves your computer, ensuring complete privacy and security.
