Do we still need spread sheets to build Apps?

If AI can resource specific information or data only, ie records of a project, and then respond to a specific search like, “What happened on March 3rd 2024”, List the jobs to be done by Martin Smith", Is there any need for a spreadsheet to be produced anymore. Surely this information can be produced on the fly with specific prompts, with **no need to have a spreadsheet . Is this possible?

I have made GPTs but would like to produce a mobile and computer app that just searched a select database.
