What CSV validation checks
Validation checks for row-shape issues such as missing fields, blank rows, and duplicate headers.
That helps you catch bad files before another system rejects or misreads them.
CSV Validator
Validate CSV files and pasted rows with delimiter detection, header checks, issue lists, and parsed previews.
Turn this off when the first row already contains data instead of column names.
About CSV validation
CSV validators catch structural problems before a file reaches an import, migration, or automation step. They help confirm that delimiters, headers, rows, and column counts line up.
Delimiter and header problems
Delimiter and header detection matters because many exports are not true comma-separated files.
Spotting semicolons, tabs, pipes, or broken headers makes cleanup much faster.
Why parsed previews help
Parsed previews show how the file is actually being read.
That makes it easier to connect each warning to the row and column layout it affects.
