Inputting data from multiple instances from multiple users into a main Excel Workbook

[smooth_beaker]

Hi,
Just a quick question from a noob with not great VBA skills...
If I have a workbook with userforms and I want to give each employee an instance of this workbook with the Userforms so they can edit existing data and add new data, how do I get their data into a main excel “master” workbook, the users workbooks were cloned from, for the manager to use. This is the last piece of my puzzle! So to reiterate, when I load the data into the main excel sheet from all these user instances, it would find if the data loaded was either an edit on an existing record or a new record to append. Hope this is possible!
Thanks for any insight!
