How to Fix CSV Encoding Errors in Excel with a Simple Python Trick
This article explains why CSV files often appear garbled in Excel, reviews two previously shared solutions, and introduces a third method—setting the file encoding to "utf-8-sig" in Python—to reliably display Chinese characters and streamline further data processing.
Introduction
The author, a Python enthusiast, previously shared articles on handling garbled characters in web crawling and now addresses a fan's question about CSV files showing unreadable text when opened in Excel.
Problem
A screenshot shows a CSV file opened in Excel with Chinese characters displayed as garbled symbols.
Solution
The third method suggested is to write the CSV file using the encoding utf-8-sig. This encoding adds a UTF‑8 byte order mark, allowing Excel to correctly recognize the file as UTF‑8 and display Chinese characters properly.
After applying this encoding, the CSV opens in Excel without garbled text, and the data can be further processed or saved as a standard Excel file.
Conclusion
The article summarizes three ways to solve CSV encoding issues in Excel, highlighting the newly added utf-8-sig method as an effective solution, and invites readers to share additional approaches.
