About the TSV to CSV Converter
This TSV to CSV converter turns tab-separated data — including anything you copy straight out of Excel or Google Sheets — into properly formatted CSV. Paste your rows, choose the output delimiter, and get clean CSV you can copy or download.
Crucially, it quotes fields correctly. Any value that contains the delimiter, a double quote or a line break is wrapped in double quotes and internal quotes are escaped, following RFC 4180. That means a cell like 'Lahore, Punjab' survives the conversion as a single field instead of splitting your columns.
You can output standard comma-separated CSV or switch the delimiter to semicolon or pipe for locales and tools that expect them. A live row and column count confirms the structure. Everything runs in your browser, so spreadsheet exports with sensitive data never leave your device.

Frequently Asked Questions
Can I paste directly from Excel or Google Sheets?
Yes — and that's the easiest way. When you copy a range of cells from a spreadsheet, it's placed on the clipboard as tab-separated values. Paste it straight in and convert to CSV without any manual reformatting.
How does it handle fields that contain commas?
Following RFC 4180, any field containing the output delimiter, a double quote or a newline is automatically wrapped in double quotes, and embedded quotes are doubled. So 'Khan, Ali' becomes "Khan, Ali" and stays a single column.
Why would I change the delimiter to semicolon?
In several European locales, spreadsheet software expects semicolon-separated files because the comma is used as the decimal separator. Choosing semicolon (or pipe) produces a file those tools open correctly without a mangled layout.
Is my data uploaded?
No. The conversion runs entirely in your browser, so exports containing customer data, financials or other sensitive content are processed locally and never sent anywhere.
