Can a prompt replace AppSheet?

Build a tool that generates a simple app view directly from an existing Google Sheet — AppSheet's actual core trick. Use Next.js/TypeScript with the Google Sheets API (OAuth) to read a connected sheet's header row as the schema and its rows as records. Generate a list view, searchable and sortable by any column, and a detail/edit view from that schema automatically — no manual field configuration needed if the sheet is reasonably well-structured. Write edits back to the same sheet via the API, using the sheet's own row identifiers so edits land in the right place, and handle the common failure case where a row was added or deleted in the sheet directly while the app was open by refetching and warning on conflict, never silently overwriting. Support a basic photo-upload field type that stores an image URL back into a cell. Do not build offline mode with sync, an automation and workflow engine, or handling for unusually structured spreadsheets like merged cells or multiple header rows — those are out of scope; this works well on a normal, single-header-row sheet and says so. Needs a Google OAuth app (free to register) with Sheets API access; no other external service required.
