CSVとJSONを相互変換。

关于CSV ↔ JSON

CSV↔JSON conversion maps tabular CSV to JSON arrays/objects and back—common for APIs, spreadsheets, and data cleaning. toco.tools supports delimiters and header rows and converts locally in your browser. Quoted newlines and deeply nested JSON may not round-trip perfectly; very large files can hit memory limits.

使用方法

  1. Paste CSV or JSON
  2. Set delimiter and headers
  3. Copy the converted output
