I'm trying to convert unstructured data found in XL into a predefined formats. The situation is that the input data will have a number of different layouts. Imagine the following situation: You have a number of suppliers that sends a batch of invoices in XL format, each one of them have their own format and they are unlikely to standardize in a predefined layout. You want to "read" from these layouts and convert them in one common layout having for example: item code, description, quantity and retail price. These are common fields that ALL invoices would have BUT some may, for example, use the wording Bar code or Unique Code or Product Code instead of "Item Code". Hence, the solution I'm looking for is to have a program to teach it that when they meet supplier name X found in row 2 cell 3 it should look for the column "Item Code" and when they meet supplier with name Y found in row 10 cell 6 they should look for column "Barcode" etc..etc.. The program would then extract the item codes, descriptions, quantities and retail prices found on each row into a new sheet/workbook in one common / standard template.
I How would you rectify such challenge?
