Office 95 (and maybe 97?) had localized versions of Visual Basic, where the keywords and VBA objects were translated into the respective local language. I’m not sure if Spanish was supported, although the following page at least lists Spanish object libraries: https://mskb.pkisolutions.com/kb/211404
In any case, you might want to install a Spanish Office 95 version in a VM for inspiration ;). Microsoft soon dropped the localized VB versions due to interoperability considerations.
Excel formulas are a perfect example of how horrible localized versions can be for coding.
I hate them, all the good guides and docs are in english but if the application is in spanish then all the function names are different. I have everything in english in my computer because of this and to avoid context switching, but when my gf asks for help I have to google every corresponding function name. Terrible design choice IMO.
