I have been using a Calc extension, XPysort, for several years in support of a user. Support for the extension has evidently been dropped, but a new onboard sort function effectively replaces it.
My problem is I have about 5 years of historical spreadsheets my user occasionally needs to access. If she tries to use the new version of Calc, these historical files won’t open correctly. She can use an older version, but then that older version cannot be used to build new sheets because the extension is not supported.
As we go forward, I can either try to maintain two versions of LO Calc for her and instruct her to use the correct one depending on the age of the file she wants to open, or I can go back in history and rewrite the files to use the new onboard function. Either of these approaches seems clunky, so I was wondering if the experts here had any advice for me.
Background of my experience can be found here.
Thanks very much for any advice
