File Diff / File Merge / File Compare

Lif Pro Tips for using this:

  • You have two scripts from different environments that you need to compare to find if anything has changed
  • You need to merge code changes from two different places into a master file
  • You have two long Excel formulas you’re trying to debug and want to know what’s different in each
  • You gave someone some content in Excel and they were supposed to add their feedback to a new column, but they changed the source data. You need to find out what they changed and move their changes to the correct column
  • You can also compare directories and get a quick readout of all diffs on all files

WinMerge to the rescue for all these situations!
