CSV TOOLS
CSV Encoding Converter
Convert between UTF-8 and Shift_JIS (CP932). Useful when Japanese text looks garbled after opening a CSV in Excel.
Choose a CSV or TXT file (up to 10 MB per operation)
Conversion happens on your device. If automatic detection is incorrect, choose the input encoding manually. Some emoji and kanji may be lost when converting to Shift_JIS.
When text looks garbled in Excel
Japanese CSV files may use different encodings, such as UTF-8 or Shift_JIS. Try selecting the input encoding and saving as UTF-8 with BOM. The best setting depends on the software that will open the file.
Before converting to Shift_JIS
Emoji and some kanji cannot be represented in Shift_JIS (CP932). Keep the original file and review the converted version.
