After having watched this video, I decided to test LF aligner for Mac: LF_aligner_3.12_mac.zip, downloaded from SourceForge
After starting the script, there are two error messages because of useless use of '\E'.
File names that contain spaces cause 'ERROR: Input file not found (No such file or directory). So you should rename your input files to names without spaces: PT1.docx, EN1.docx etc.
As shown in the video, any modified Excel file isn't used for creating the TMX. Instead the unmodified version of the Excel file is used. So you'll have to run the script TMX_maker_2.23.command manually. Could this be fixed, please?
There is a Join (Merge) command, but no Split command. Could this be added, please?
