The client was looking for an easy alternative to update export cash receipts against open invoices in Netsuite.

General Approach But Inefficient

CSV upload is the general approach to update the Netsuite data.  The challenge with the CSV approach is that you must have the hard link to reference appropriate entity IDs, items, and other information before the data will successfully import.  When getting data from a third party source that has no clue about your Netsuite business system, you are confronted with massaging the data in a spreadsheet and use power user functions, such as VLookup, to reference the proper information before it can be uploaded to Netsuite.All of this data preparation work is a repetitive activity and here comes the need of automation, but traditional types of automation may be unfeasible because of higher cost of development and setup.

While at Excel end we can use macro based on VBA, it empowers the user in Excel to write functions to automates the tasks.
