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.
