How to Convert Excel to CSV Without Unicode Errors
Secret to converting Excel (XLSX, XLS) to CSV format while preserving UTF-8 encoding and preventing character corruption.
When exporting data from Excel to CSV for database systems, the most common error is Vietnamese characters turning into strange symbols.
Why does RedConvert solve this problem?
Normally when saving CSV with default Excel, the software uses ANSI/Windows-1252 encoding. RedConvert automatically inserts a standard BOM (Byte Order Mark) UTF-8 at the beginning of the CSV file, helping all software like Google Sheets, MySQL, Notepad++ recognize Vietnamese correctly 100%.
