My CSV opens with everything in one column

The file opened, but every row sits in a single column with the separators still visible in the text.

Why it happens

  • The name of the format promises a comma and the file often does not contain one.
  • Which separator a spreadsheet expects when you double-click a file comes from regional settings rather than from the file.
  • Some exporters try to settle it by writing a sep= line as the first line of the file.
  • A tab-separated file saved with a .csv extension produces the same symptom for the same reason.

What to do now

  1. Open it through the import dialog rather than by double-clicking: Data → From Text/CSV, where the delimiter is something you choose rather than something you inherit.
  2. Look at the raw file in a text editor to see which separator it actually uses before choosing.
  3. Do not fix it by replacing semicolons with commas across the file.

Next time

The delimiter is sniffed per file rather than assumed, and a tab wins over a comma, which wins over a semicolon, so a European semicolon export and a tab-separated paste land the same way a plain CSV does.
