A simple CSV ↔ JSON ↔ YAML workflow in the browser

Spreadsheets, APIs, and config files rarely speak the same dialect. A short local conversion pass often beats writing a one-off script for a five-minute task.

Spreadsheet to JSON

Export CSV from your sheet, then open CSV to JSON. Headers become object keys. Check a few rows for quoted commas and empty cells before you feed the JSON into an importer.

JSON back to CSV

JSON to CSV is the reverse path: arrays of objects become rows. Nested objects may need flattening first — keep structures shallow when the destination is Excel or Google Sheets.

Configs in YAML

Ops and Kubernetes-style configs often prefer YAML. JSON to YAML converts either direction so you can edit in the format you like and paste back what the tool expects.

Validate along the way

Run awkward JSON through the JSON Formatter before converting. Invalid JSON wastes time in every downstream step.

Tips for clean conversions

1. Prefer UTF-8 CSV exports.
2. Keep a sample of three rows to verify types (numbers vs strings).
3. Do not upload customer exports to public converters when a browser tool will do.
