React or Angular Project -- 2

I have some clients that need a way to import, edit, and export data. I’d like to offer them a User Web interface to Import csv, iif, xml, and xls files into a database, (really easy to decipher each). Edit records with rule matching and inline, then export csv. User authentication and export limits. I have a detailed outline to keep the guesswork to a minimum, which will save on time/cost
