About this tool
CSV (Comma-Separated Values) is the most widely used plain-text format for tabular data. However, not all CSV files follow the same conventions — some use semicolons or tabs as delimiters, some have inconsistent quoting, and some contain extra whitespace around values. A CSV formatter re-parses a CSV file and outputs it in a clean, consistent format using your preferred settings. This makes CSV files compatible with systems that expect specific formatting conventions.
