471806 Merge excel csv spreadsheets into one spreadsheet
N/A
Paiement à la livraison
I need an excel macro or a php script with a simple upload form, that will do the following for me:
I will have up to 12 excel csv spreadsheets. They will have exactly the same columns (12). The entries in the first column will act as the unique identifier. Using this unique identifier, the data (numbers) in the last 6 columns must be added together for the result spreadsheet. Columns 2-6 will use the data from the first spreadsheet.
I am attaching two spreadsheets with the desired result spreadsheet as an example. The actual spreadsheets will have up to 10 000 rows.
