I'm trying to fetch data from multiple google sheets into another google sheet. The sheets contain data of the customers on a monthly basis. I want to create a master sheet with the complete customer data. I tried the ImportRange formula but it does not take the other sheet's data and the previous data gets deleted.
Suppose there are 3 Google Sheets, namely, "Jan", "Feb", "March" I have a Google sheet named "Master customer Data", I want to add the complete customer details in this sheet ( if in the future the data gets updated (in "Jan", "Feb", and "March" Sheets) then this sheet ("Master customer Data") needs to be updated automatically).
P.S: The data contains: DOB, Names, contact numbers and User IDs (mix of numbers and alphabets)
Thank you
