About this tool
Paste CSV in any separator and view it as a clean table, ready to copy or download as normalized comma-separated output.
The CSV Formatter takes raw, inconsistent, or minified Comma-Separated Values data and transforms it into clean, properly aligned, and consistently structured tabular output. It's essential for developers, data analysts, and anyone working with spreadsheet exports, database dumps, or API data where CSV formatting is mangled by copy-paste operations, log aggregation, or data pipeline processing.
The formatter detects and handles common CSV issues: inconsistent delimiters (commas vs semicolons vs tabs), mismatched quoting, embedded newlines within fields, and UTF-8 encoding problems. It normalizes column alignment, ensures proper quoting of fields containing special characters, and can add or remove headers for clean tabular display. The result is well-structured CSV that opens correctly in Excel, Google Sheets, or any data tool.
For teams migrating data between systems, cleaning up exports from legacy applications, or preparing datasets for import, this tool ensures CSV integrity without spreadsheets or custom scripts. All processing is client-side — your data, which may contain personal records, financial data, or proprietary information, never leaves your browser.
