2. Delete any local copies you have of the WORDSABC and WORDS123 text files.
I've set up automation to keep the WORDSABC and WORDS123 files up-to-date with the Google Sheet. It runs either weekly or on-demand, so if you really like working with these text-based formats, you can find current versions there. However, the Google Sheet has much more powerful search capabilities and is still recommended to use.
While I was at it, I also set up some scripts to calculate recent questions about numbers of withdrawn words in a round, and moved the "back to back" streak reports from the google sheet to another text-based report.
