About CSV Encoder & Delimiter Fixer
CSV Encoder & Delimiter Fixer is a comprehensive tool for repairing and converting CSV file formats. Change delimiters (comma to semicolon, tab to pipe, etc.), fix encoding issues (UTF-8, BOM, Latin1), normalize quotes and escapes, convert line endings, and repair malformed CSV files—all processed locally in your browser.
What is CSV Encoder used for?
CSV Encoder fixes common CSV formatting problems: changing delimiters (e.g., converting European semicolon-separated files to standard comma-separated), repairing encoding issues (UTF-8 vs Latin1), adding or removing BOM (Byte Order Mark), normalizing line endings (Windows CRLF vs Unix LF), and fixing malformed quotes or escape characters.
What is BOM and when should I use it?
BOM (Byte Order Mark) is a special character sequence at the start of UTF-8 files. Some applications (especially Microsoft Excel) require UTF-8 BOM to correctly display non-ASCII characters (accents, Chinese, Arabic, etc.). Enable 'Add BOM' if you're creating CSV files for Excel with international characters.
How do I fix Excel CSV delimiter issues?
Excel in different regions uses different default delimiters: English Excel uses commas, European Excel uses semicolons. If your CSV file shows all data in one column, the delimiter is wrong. Use this tool to auto-detect the input delimiter and convert it to your Excel's expected format.
What does 'Fix malformed quotes' do?
This option repairs common quoting errors: unescaped quotes inside fields, missing closing quotes, and inconsistent quote usage. It ensures all fields with special characters (quotes, commas, line breaks) are properly quoted and escaped according to RFC 4180 CSV standards.
Can I convert between different encodings?
Yes. The tool detects input encoding (UTF-8, Latin1, Windows-1252) and converts to your selected output encoding. This is useful when importing CSV files from legacy systems that use non-UTF-8 encoding, or when you need to ensure UTF-8 compatibility for modern applications.
Is my data secure?
Absolutely. All CSV processing happens locally in your browser. Your files and data never leave your device, ensuring complete privacy for sensitive information like customer data, financial records, or proprietary datasets.
