Detect CSV delimiter
CSV-like files may use commas, semicolons, tabs or pipes depending on the source system. Paste a sample to get a delimiter guess and separator counts. It is useful when opening exports, fixing import settings or diagnosing malformed data files.
Choose the right parser
Delimiter detection works best when several rows use the same structure.
