CSV SPLITTER

Split a CSV by Column Number or Header Name

Choose a column to create one CSV per value. Auto-detect UTF-8 or Shift_JIS input, or select CP949, Big5, or GB18030 manually. Choose any of the five encodings independently for output. Files up to 50 MB stay in your browser.

Split a CSV by column value

Choose one column and download a ZIP with one CSV per value. Select it by one-based position or header name.

How it works

  1. Choose a CSV and confirm its encoding and header setting.
  2. Set the split column, blank handling, and whether key whitespace is ignored.
  3. Run the split and download the CSV files and row report as a ZIP.

Before you start

  • Limits: one 50 MB CSV, one split column, and 100 output files.
  • A non-UTF-8 output stops instead of replacing unsupported characters; choose UTF-8 when needed.
