GST Refund Data Compilation

I need help consolidating all the information required for an upcoming GST refund claim. The source material is already in Excel: separate workbooks for purchase invoices, sales invoices, and expense receipts.

Your task is to merge these datasets into one clean, well-structured spreadsheet that clearly distinguishes the three invoice types while keeping every field intact (invoice number, date, supplier/customer, taxable value, GST amount, etc.). I am not requesting any extra validation beyond ensuring cells are accurately copied over; adherence to formal GST validation rules is not necessary for this job.

Please deliver a single Excel file that I can review and forward to my accountant for the claim submission.
