Convert Excel to CSV using UTF-8 encoding

On my mac OS X, Excel itself cannot directly save file as UTF-8 encoding. Here are the steps we can workaround.

• Save file to UTF-16 text file
  Excel - Save as ... select "UTF-16 Unicode Text (.txt)"
• Convert .txt file to UTF-8 format
  Sublime Text -> Save with Encoding -> Select UTF-8
• Replace Tab with comma
  Sublime Text -> Replace using regular expression (\t to replace ,)
• Rename file from .txt to .csv extension
