The case study for Master Spreadsheet Editor, a Google Sheets Add-On that enables a user to make changes to one spreadsheet that are then applied to a number of other spreadsheets. This tool works well for teams with multiple team members using identical spreadsheets, such as data entry specialists. For example, if a formula needs to be changed across all spreadsheets, this tool would allow a manager to do so from one location, instead of manually changing it in each spreadsheet.

The code for the app is available here: https://github.com/luisdasilva-contact/Master-Spreadsheet-Editor
