Frequently Asked Questions
Common questions about Csv Formatter formatting answered
Yes, our CSV formatter is completely free with no registration required. All processing happens in your browser.
We support comma (,), semicolon (;), tab, and pipe (|) delimiters. You can switch between them to match your regional or application requirements.
Yes, our formatter fully supports RFC 4180 compliant CSV including quoted fields, embedded commas, and multi-line values within quotes.
Yes. Select your input delimiter and choose a different output delimiter. The formatter will re-parse and re-output the data with the new delimiter.
Column alignment adds padding spaces so each column has a consistent width. This makes the CSV much easier to read in plain text editors.
Fields containing commas, quotes, or line breaks must be wrapped in double quotes, and quotes inside quoted fields are doubled (""). RFC 4180 also specifies CRLF line endings, though most tools accept LF. The formatter enforces the quoting rules and normalizes line endings to one style you choose.
The delimiter is inferred per file by counting candidates (, ; \t |) outside quoted sections on the first rows - the same heuristic Excel's import wizard uses. Encoding is assumed UTF-8; a BOM is detected and stripped or preserved on output depending on the option, since Excel needs the BOM to recognize UTF-8.
The report lists rows whose field count differs from the header - the most common CSV defect, usually from unquoted commas or an embedded newline. Those rows are kept verbatim and flagged, because guessing where to add quotes risks silently corrupting data.
