When we scrape data from Non-English languages and give you a CSV file, the data may appear corrupted or unreadable (when you double click and open the file in Excel).
This issue occurs because we scrape the data as unicode text, but Excel reads CSV files in non-unicode by default.To configure Excel to use unicode on your exported CSV reports:
You now have a properly formatted (and unicode-friendly) Excel worksheet.
If you would like to know more about encoding and characters sets, here is an excellent article.
Sometimes, despite opening the file with the correct encoding, Excel will show multi-line strings on separate lines in Excel as the next row of the data. The solution to that problem is something related to BOM
You need to download Notepad++ for free at http://notepad-plus-plus.org/ and then open the CSV file in it and then click the Encoding menu and check the entry related to UTF-8 and BOM
Then Save the file and Open it in Excel and the issues should be fixed.
