    Über dieses Tool

    Turn a spreadsheet into an array of JSON objects, using the header row as each object’s keys — handy for feeding spreadsheet data into an app, API, or script. Conversion runs entirely in your browser.

    Which row becomes the JSON keys?

    The first row of the first sheet is used as the property names for every row after it.

    What happens with empty header cells?

    Empty header cells are automatically named col1, col2, and so on.

    Does it read every sheet in the file?

    Only the first sheet is converted.
