(URGENT) Search for matching data, copy and pasting from a closed excel file

Hi Everybody,

I have three separate excel files: a closed Interest spreadsheet, a closed Balance spreadsheet, and an open Database spreadsheet. The two closed excel files change every quarter and I want the updated data be copied into the Database file. I need a code/macro in “Database.xlsm” that on a click of a button once every quarter, it would search for the matching “ID” in the other two closed excel files, copy the “Interest” and “Balance” data for that “ID” and paste it in the “Interest” and “Balance” fields for the relevant quarter in the “Database.xlsm”. I wouldn’t want the next quarter information overwrite the previous quarter’s data and would want to keep the old data. This is a tough one for me and I would really appreciate it if you guys could help me with this.
