I need a straightforward app—accessible both in a browser and on iOS / Android—that lets me drop in a database file, have its tables parsed automatically, and then push each table straight into either Google Sheets or downloadable Excel workbooks. Here’s the flow I have in mind: 1. Import: the user selects or drags-and-drops a database file of unknown type. For now I’d like the app to detect or gracefully ask whether the file is SQL, CSV, or JSON, then continue. 2. Parse: every table (or top-level JSON array / CSV sheet) is listed, with a quick preview so the user can deselect anything they don’t need. 3. Export: one click should create a new Google Sheets workbook—one tab per table—or bundle the same data into an .xlsx file for direct download. Deliverables • Responsive web interface plus companion mobile build (Flutter or React Native are fine, but I’m open) • Clean, well-commented source code and brief setup guide • Deployment script or instructions so I can host the web version on my server and submit the mobile builds to the app stores • A short test file set showing the import-parse-export cycle working for SQL, CSV and JSON Acceptance I’ll consider the project complete when I can: • upload a sample database, see the tables detected correctly, and send them to Google Sheets without manual tweaks; • repeat the same steps on my phone; • review your code and deploy it myself following your instructions. If you’ve built similar ETL or importer tools before, let me know and feel free to suggest the best stack for a quick, maintainable solution.
