Data Converter

Working with data across different formats is one of those everyday frustrations that adds up fast. You get a CSV from a client, but your API expects JSON. You're parsing XML from a third-party service and need YAML for your config file. Each conversion used to mean installing a library, writing a script, or uploading your data to some unknown server. Diztool's Data Converter works entirely in your browser. Your data never leaves your device — no upload, no server, no account needed. How to use it: Start by choosing your input format from the left dropdown — JSON, CSV, XML, YAML, or TOML. Then paste your data into the input box. The converter validates input as you type, so you'll instantly see if something's malformed. Pick your output format from the right dropdown and click Convert. The result appears immediately, ready to copy. Tips for cleaner conversions: When converting CSV to JSON, make sure your first row contains headers — those become the JSON keys. Empty cells become null values, which is usually what you want for downstream APIs. For JSON to CSV, nested objects get flattened. A field like {"address": {"city": "Delhi"}} becomes address.city in the CSV. If your JSON is deeply nested, flatten it manually first. XML to JSON is useful when consuming RSS feeds, SOAP responses, or legacy data. Attributes are preserved as @attr keys. When converting in the other direction, JSON arrays map to repeated XML elements. YAML to JSON is common when moving configuration values into API calls. JSON to YAML is often needed for Kubernetes manifests, Docker Compose files, or GitHub Actions workflows. Common use cases: API development — Test payloads by quickly converting between JSON and CSV to check your data shape before a real call. Data analysis — Get a JSON API response into CSV so you can open it in Excel or Google Sheets without writing any code. Config files — Convert between YAML and JSON for Docker, CI/CD pipelines, or cloud infrastructure configs. Data migration — Transform a database export into the exact format your import tool expects, without writing a script. The converter handles pretty-printed and minified JSON equally. For CSV, comma, semicolon, and tab delimiters are auto-detected. YAML supports multi-document files separated by ---. All processing happens in your browser using JavaScript — no backend, no logs, no third-party access to your data.
