QR Code Web App Development

I need a straightforward web application to generate and store dynamic editable QR codes. The code data, comprising short URL reference numbers and assigned telephone numbers, should be downloadable for easy export to an Excel spreadsheet. This spreadsheet will be used to produce stickers, each with a unique code, sent to specific customers. Upon receiving their sticker, customers should be able to edit their phone number by entering the code's reference number and updating their information.
