Convert YAML config to JSON for tools, APIs, and scripts that prefer JSON syntax.
YAML to JSON is what you want when a tool that only speaks JSON needs to consume a config that was authored in YAML. Most CI systems, JavaScript scripts, and REST APIs prefer JSON. The conversion is lossless in structure - only the syntax changes.
We parse YAML with the yaml library (full YAML 1.2 support), then stringify to indented JSON. Multi-document YAML files (separated by --- markers) emit only the first document; use a downstream split for multi-doc workflows. Comments are dropped (JSON doesn't support them). Everything runs locally.
YAML is a human-friendly data serialization format - indentation-based, less noisy than JSON, ideal for config files. Used by Kubernetes, CI pipelines, and most modern DevOps tooling.
JSON (JavaScript Object Notation) is the lingua franca of structured data on the web. Arrays, objects, strings, numbers, booleans. Read by every modern programming language.
Drag a YAML onto the converter above, or click the box to pick one from your device.
We've preselected JSON as the output format. Change it from the dropdown if you want a different target.
Click Convert and wait for the progress bar to finish. Download the JSON when it's ready.
Convert JSON config files to the more human-readable YAML format - Kubernetes, GitHub Actions, Docker Compose love it.
Convert a CSV file to JSON in your browser - perfect for piping spreadsheets into scripts, APIs, or LLMs.
Flatten a JSON array of objects into a CSV file - paste into Excel, Google Sheets, or any spreadsheet tool.
