To create your own template, you must first be a paying client, as this feature is not available to freemium users.
Once you have access, start by making a sheet in Excel with the structure you want. Next, go to the "Outputs" section and select "Library”, create a new output by uploading your Excel file and activate it. Once the file is uploaded, you will find your output under the tab “Activated”. Click on the three dots next to it and select "Data Appearance". From there, you can customize what data appears in each column to match your template.
