How to convert json to a github actions workflow yaml
- Step 1Structure the JSON as a workflow definition — The JSON should have on (triggers), jobs (object of job definitions), and optionally env (workflow-level environment). Each job needs runs-on, and steps (array of step objects).
- Step 2Convert to YAML — Paste the JSON and click Convert. The output YAML preserves the GitHub Actions structure. Multi-job workflows with needs dependencies are correctly nested.
- Step 3Review the output for GitHub Actions syntax — GitHub Actions YAML has specific requirements — expression strings like ${{ secrets.TOKEN }} should remain as quoted YAML strings. Review any expression values in the output to ensure quoting is correct.
- Step 4Save to .github/workflows/ — Save the output as a .yml file in your repository's .github/workflows/ directory. Push to GitHub and check the Actions tab to confirm the workflow is recognized and the trigger conditions are correct.
Frequently asked questions
Why does GitHub Actions sometimes reject YAML that looks correct?+
GitHub Actions uses a strict YAML parser that rejects certain edge cases: reserved words (on, yes, no) must be quoted as strings, and boolean-looking values like 'true' should be quoted if you intend them as strings. Review the converted YAML and add quotes around any keys or values that could be interpreted as YAML primitives.
How do I represent a matrix strategy with multiple dimensions?+
Structure the matrix as a nested JSON object: { "strategy": { "matrix": { "os": ["ubuntu-latest", "windows-latest"], "node": [18, 20] } } }. The converter produces the correct YAML matrix block that GitHub Actions uses to generate parallel job runs.
Are workflow secrets and token names transmitted to JAD Apps?+
No. Conversion runs entirely in your browser using js-yaml. Workflow content including ${{ secrets.TOKEN }} references and environment variable names is never transmitted to JAD Apps servers.
