CSV Escape / Fix
Rescue your data from corrupted or poorly formatted CSV files. Common issues like unescaped quotes, inconsistent line endings, or commas within fields can break standard parsers. Our CSV Escape / Fix tool analyzes your file, identifies these structural errors, and automatically applies RFC-4180 compliant escaping and formatting. It's the ultimate 'repair' tool for exports from legacy systems or tools that don't handle CSV standards correctly. Everything happens in your browser, keeping your data secure.

Questions People Ask
Honest answers about how this works.
What is RFC-4180?
Short answer: It is the published standard that defines how CSV files should be written. It specifies that fields containing the delimiter, double quotes, or line breaks must be wrapped in quotes, with internal quotes doubled. Following it ensures your file opens cleanly in Excel, databases, and programming libraries.
Can I reallyt fix encoding issues?
Short answer: Yes, within limits. The repaired file is always exported as UTF-8, so a legacy export re-saved through the tool comes out in the encoding that Excel, databases, and web apps expect. If the source text already looks garbled on screen, fix the original code page first, then let the tool handle the CSV structure.
Does repairing rewrite or drop any of my data?
Repair changes quoting, delimiters, and line endings, not your values. Fields containing the delimiter, embedded quotes, or line breaks get wrapped and escaped correctly, rows stay in their original order, and the header row is preserved. You can preview the normalized rows before downloading to confirm nothing was lost.
