Software always needs to balance performance and features. This page collects options to tweak that balance. Be aware that whenever you choose performance, you lose features, there is no free lunch. And don't expect miracles, usually you gain only 10-20% speed. This is mostly for large files, and heavy use. Mostly it's OK to keep the defaults.



  • Try to support Libre Office: if you don't use Libre/Open Office (only needed for ods files), switch this off to save a few seconds loading time
  • Try to support MultiTerm: if you don't want to create sdltb files, switch this off to save a few seconds loading time
  • Silent Mode: You can shave off a few percentage points by disabling logs and progress bar updates. Not recommended unless you batch process massive files
  • Fast Mode: Opening large and complex spreadsheets can take quite long. Much of that time is spent verifying if rows, columns, or pages are hidden. If they are, the converter will also ignore them.
    In most cases, though, users don't hide data and don't need that much precision. So by default, this setting is disabled. Faster, but if you have a hidden data, it will still be converted. Set to true if you don't want hidden content to enter your termbase.
  • Do not format Excel: this is probably the biggest time saver. The converter applies formatting to Excel, to make it more readable. If you are OK with plain data, you can convert roughly twice as fast.
  • Verify and fix XML files: Some XML files out there are slightly wrong. They may contain invalid character references, or broken Unicode. The converter can fix some of these problems. It's usually best to activate the option, but it takes a little bit of time. So if you convert very large xml files, and know they are valid, disable it.
