MySQL Mobile Number Export

I need a specialist who can connect to our Android app’s MySQL backend and extract only the authorised users’ mobile numbers. Once pulled, the data has to be organised cleanly into both a CSV file and an Excel spreadsheet, ready for immediate use in our marketing dashboard. Accuracy is critical, so please make sure no stray characters slip through and remove any obvious duplicates you encounter before delivery. Security matters just as much as accuracy; handle credentials through a secure channel and work on a copy of the database whenever possible.

You’ll be working directly on the live server environment, so solid experience with MySQL, efficient SQL queries, and safe data-handling practices are mandatory. If you have built similar export pipelines or automated user-data dumps before, let me know—sample scripts, GitHub links, or a short walkthrough of past projects will help me gauge fit quickly.

Deliverables
• CSV file containing all authorised mobile numbers
• Excel file containing the same data, formatted identically
• Brief read-me outlining the exact query used and any clean-up steps performed

I’m happy to discuss timelines and payment once I’ve reviewed your relevant MySQL extraction work.
