Tutorial: Comparing Excel Files and Emailing Reconciliation Errors

In this tutorial, we will create an automation to compare the amounts in a spreadsheet that contains invoices with the amounts from a CSV file that contains a summary per supplier. If any reconciliation errors exist between the files, we will create a CSV file with details and send the file by email.

We will create a project with the following activities:

Two Use Excel File activities to indicate the Excel file with the invoices and the file where we want to reconcile the data.
A series of Write Cell activities to add two column headers to the reconciliation Excel file and to calculate the sum of invoices for one supplier and the difference between that sum and the amount in the initial summary. We will add a Copy Range activity to copy the formulas we added for one supplier to all the rows in the sheet so that we can perform the same calculations for all the suppliers, and then add one more Write Cell activity to add the total difference to a cell.
An If activity where we will add a condition that if there are reconciliation errors (the sum of differences is greater than 0), a CSV file with details should be created and emailed to a specified address. For the email tasks, inside the If activity we will add a Use Desktop Outlook App activity to indicate the Outlook account we want to send the mail from and a Send Email activity inside Use Desktop Outlook App.

Set up the project and get the necessary files.
1. Create a new blank project using the default settings.
2. Download and extract the archive with the automation project in this tutorial using the button at the bottom of this page. Copy the folder data to your project folder.

The invoices and summary data are copied to the reconcile.xlsx file, the calculations are performed and, because the total amount in the invoices does not match the one in the summary for one of the suppliers, the Summary sheet of the reconcile.xsls file is copied to a CSV file whose name includes today's date, the file is attached to an email and sent to the specified address. In the file, you can identify the supplier with reconciliation errors by the value in cell D3 that is greater than 0.
