TXT to CSV online vs desktop apps

Manual find-and-replace is error-prone. Desktop tools often require installation. Many online tools upload your files. Our converter is free, runs in the browser, and keeps your data on your device while supporting multiple delimiters and encodings.

Tips for best results

Before you convert:

• Choose the delimiter that matches your text (comma for CSV, tab for TSV).
• Use first line as header when your first line contains column names.
• Select the correct encoding (UTF-8 for most files).
• Use batch conversion for multiple files.
• Open the CSV in Excel or Google Sheets to verify columns.
• Semicolon is common in European locales where comma is the decimal separator.
• Keep backup of original TXT if you need to re-convert with different settings.
