    Good to know

    • The input should be a JSON array of objects (for example [{"name":"Ann","age":30}, …]); each object becomes a row and each key becomes a column.
    • Column headers are taken from the object keys, and values with commas or quotes are automatically escaped so the CSV opens cleanly.
    • CSV is a plain-text format that every spreadsheet program can import directly.
