Convert any text file to CSV in three simple steps.
Paste your tab-delimited, comma-separated, or any delimited text data directly or upload a file.
Select the delimiter used in your text data � comma, tab, semicolon, pipe, or a custom separator. Auto-detection is on by default.
Copy the properly escaped CSV to your clipboard or download it as a .csv file.
A TXT to CSV Converter transforms plain text data into Comma-Separated Values (CSV) format. Text files often contain tabular data separated by tabs, commas, semicolons, pipes, or other delimiters. This tool parses the delimited text and produces clean, properly escaped CSV output ready for import into spreadsheets, databases, or data processing pipelines.
Whether you have a tab-separated export from a database, a pipe-delimited log file, or a custom-formatted text dump, this converter handles it all. It auto-detects the delimiter used in your data and produces RFC 4180-compliant CSV output with proper quoting and escaping.
Automatic delimiter detection
The tool analyzes your text and detects whether it uses commas, tabs, semicolons, pipes, or another delimiter.
Client-side processing
Your data never leaves your browser. No uploads, no servers, no privacy concerns.
RFC 4180-compliant output
Fields containing commas, quotes, or newlines are properly quoted and escaped per the CSV standard.
Multiple delimiter support
Supports comma, tab, semicolon, pipe, and any custom delimiter you specify.
The converter samples the first few lines of your text and counts occurrences of common delimiters (tab, comma, semicolon, pipe). The delimiter with the most consistent column count across rows is selected. You can override auto-detection by choosing a delimiter manually.
Any delimited text format: tab-separated values (TSV), pipe-separated values (PSV), semicolon-separated, custom delimiters, or even fixed-width text. The tool handles all common text-to-CSV conversion scenarios.
Fields that contain the delimiter character, double quotes, or newlines are automatically wrapped in double quotes with internal quotes escaped as double-double quotes (""), following the RFC 4180 CSV standard.
No. All conversion happens entirely in your browser using JavaScript. Your data is never sent to any server. You can verify this by disconnecting from the internet and using the tool offline.
