There are two types of excel uploads
Single Activity Upload (Bulk Upload)
Single site upload is most commonly used by a user who has a spreadsheet for a particular activity where it is more time consuming to input the data one at a time manually such as an electricity meter supplier statement for 12 months, or daily meter readings for an electricity meter. It can only upload one spreadsheet per activity per building at a time. There can be multiple activity types in the spreadsheet, but only one activity.
Multi-Activity Excel Upload
The Multi-Activity excel upload is used when the user wants to upload a spreadsheet or csv file that contains data for multiple activities of the same category. For example spreadsheet contains electricity meter data from 55 buildings.
