Wordfast Translation Memory

The Wordfast format, as used by the Wordfast translation tool, is a simple tab delimited file.

The storage format can read and write Wordfast TM files.


  • Escaping – The format correctly handles Wordfast &'XX; escaping and will unescape and escape seamlessly.
  • Soft-breaks – these are not managed and are left as escaped
  • Replaceables – these are not managed
  • Header – Only basic updating and reading of the header is implemented
  • Tab-separated value (TSV) – the format correctly handles the TSV format used by Wordfast. There is no quoting, Windows newlines are used and the \t is used as a delimiter (see issue 472)
