CSV Localization


The CSV format is not a well defined standard. There are several variations: field separators, quoting, escaping, encoding and others.

So LingoHub has defined a CSV standard that is suitable for localization and based on RFC4180.


  • encoding should be UTF­-8 (but you can export to other encodings)
  • the markup follows the RFC4180 standard, which means:
    • comma (,) will be used as column separator
    • all values have to be quoted with double ­quotes (“)
    • quotes can be escaped using double double­ quotes, eg.: “Hello, “”LingoHub”””
    • the line ending is always CRLF
    • quoted values can span multiple lines
    • the placeholder syntax is: {placeholder_name}
  • the first line is the header and must have the following columns:
    • “Title” constant
    • “Description” constant (this column is optional)
    • the next columns hold the ISO639-1 code for the languages in the file, eg.: “en”, “pt-BR”
