How it works
The delimiter (comma, semicolon, tab or pipe) is auto-detected from the first line. Cleaning then trims whitespace from every field, drops rows and/or columns that are entirely empty, and can normalize line endings to Windows-style CRLF. Quoted fields, embedded commas and multi-line fields are parsed correctly.
Frequently asked questions
Which delimiters are supported?
Comma, semicolon, tab and pipe are auto-detected from the first line; mixed-delimiter files are not supported.
Is this different from the duplicate-row remover?
Yes - this tool normalizes formatting (whitespace, blank rows/columns, line endings); it does not compare rows against each other for exact duplicates.
