Hello i was wondering if it was possible to choose a csv file from a folder in the phone and just use it as a database, i have many csv files to choose from but i don't know how to choose from a folder in the phone
Why dont you use the search function? Search results for 'Working with csv' - MIT App Inventor Community
you can choose a csv file using the file picker or csv, but you can`t use it as database directly... the file component is only able to read the complete file or write the complete file or append rows to the file
to work with an offline database you usually would use sqlite, you can access sqlite by an extension, for example App Inventor Extensions: SQlite | Pura Vida Apps There are also other sqlite extensions around

It should be easy enough to import your csv data into an sqlite table. I have done it in the past with downloaded csv data from Google Sheets.
