Employ an Excel Workbook document to perform calculations, logical operations, and data manipulation.
Please follow a few simple steps to make your Excel Workbook available in Integromat.
You can update you Excel Microservice by altering the Excel Spreadsheet document on you pc/mac with new logic, calculations and data, and then uploading it back to the web service that you created for that Excel Spreadsheet.
If you made changes so that input and output cells are placed differently in the document, you will have to change the configuration of the document accordingly. When configurations is changed test the service and only then launch a new version of it. When your Excel web service is launched you will have to reconfigure your Excel Spreadsheet Module in Integromat scenarios where it is used to get the latest configuration.
If you didn't make changes that can influence position of your input and output cells, then you can simple upload the document, test the service and launch a new version. In this case you don't have to reconfigure your Excel Spreadsheet Module in Integromat scenarios.
