Hi Community,

I'm busy with the following little project:

Given is an input table in Excel. (input.xlsx)
It contains following fields:
ID, name, address, postal code, date_of_start (headings are in first row A1, A2, A3, A4, A5)
This table has 300.000 records. (data start at row 2)

I would like to create a new Excel File (lookup.xlsm) where I can filter the data in the original Excel-file. (filter based on name and address)
In the filtered results, it has to be possible to change/update the value of "date_of_start" and that should be saved in the original table. (input.xlsx)

=> is such thing possible with Excel/VBA?

I discovered the Excel Advanced Filter function, but my need is a little bit more complex than that I guess:
- I need to have 2 files: one with the data (backend) and one with the search & update function (frontend).
- the changes made in the frontend has to be saved in the backend.
- The use of MS Access is not possible.

Any advice how to manage this would be appreciated.

(with Excel Advanced Filter, I nearly had what I wanted, but the problem is that when you use "copy to another location", you can't make changes in the filtered results, and that's what I need)
