Data Conversion

Moving data between formats shouldn't need a throwaway script. This set converts JSON to and from YAML, CSV, URL query strings, and Python dict/list literals, and converts between Postman collections, OpenAPI specs, docker run CLI commands, and Docker Compose or Kubernetes manifests, all reversible and all in the browser.

Convert JSON trees to clean, indented YAML for Kubernetes, Compose, and configs.

Parse YAML configs, manifests, or snippets to clean formatted JSON.

Deterministic CSV parser with custom delimiters, header toggles, and auto-typing.

Export array of JSON objects to RFC-4180 CSV with custom delimiters.

URL encode deep objects with bracket, dot, or JSON nesting notations.

Parse URL query parameters, full URLs, and bracket structures to JSON.

Render JSON as a Python dict/list literal. null → None, true → True, false → False.

Convert Python dict/list literals to JSON. Handles None, True, False, and single quotes.

Convert a Postman Collection v2.1 JSON to an OpenAPI 3.0 YAML spec. Extracts endpoints, params, and request bodies.

Convert an OpenAPI 3.0 JSON or YAML spec to a Postman Collection v2.1 with folders, bodies, and example responses.

Convert Docker Compose YAML services to Kubernetes Deployment and Service manifests.

Convert docker run CLI flags, ports, volumes, env vars, and resource limits into clean docker-compose.yml manifests.
