Frequently Asked Questions
What is the difference between TXT and CSV files?
TXT files are plain text with no specific structure, while CSV (Comma-Separated Values) files are structured with values separated by commas. CSV files can be opened directly in spreadsheet applications like Excel, Google Sheets, or Numbers.
What delimiter should I choose?
Choose Tab if your text has tab-separated columns (common in database exports). Choose Comma if values are comma-separated. Choose Semicolon for European data where comma is the decimal separator. Choose Space for space-separated log files.
Is my data sent to a server?
No. All conversion happens directly in your browser using JavaScript. Your data never leaves your device, making this tool completely private and secure for sensitive information.
Can I convert TSV (Tab-Separated Values) to CSV?
Yes! TSV files are text files with tab delimiters. Simply paste your TSV content and select 'Tab' as the input delimiter to convert it to CSV format.
How are special characters handled?
Our converter properly escapes special characters according to CSV standards. Values containing commas, quotes, or newlines are wrapped in quotes, and existing quotes are doubled to maintain data integrity.
What is the maximum file size I can convert?
Since conversion happens in your browser, the limit depends on your device's memory. Typically, files up to 50MB work well. For larger files, consider using command-line tools or splitting the data.
Can I open the CSV file in Excel?
Yes! CSV files are fully compatible with Microsoft Excel, Google Sheets, Apple Numbers, LibreOffice Calc, and most other spreadsheet applications. Just double-click the downloaded file.
How do I convert multiple TXT files?
Currently, you need to convert files one at a time. For batch conversion needs, we recommend using command-line tools or contacting us for a custom data processing solution.
