I'm trying to use an excel file as a database and the app constantly needs to read and modify the file. As explained in this Q&A, it is necessary to create a copy of original excel file and all the modification has to be done there. Is there anyway to modify the excel file without creating a copy because I'll be using the file name at another instance to read it.
Also, I'd like your opinion on which one would be efficient as a database for offline access? An android sqlite or excel file ?
