What the CSV Delimiter Detector and Converter Checks

  • Source delimiter sniffing

    The parser scores commas, tabs, semicolons, and pipes from the first few rows.

  • Header and row parsing

    Rows are parsed with CSV quoting rules before being written with the target delimiter.

  • Target delimiter selection

    Comma, semicolon, tab, and pipe outputs are supported.

  • Uneven row warnings

    Rows with a different cell count from the header are reported.

  • Safe cell escaping

    Cells are quoted in the output when the target delimiter or quotes require it.
