Data Summarization by group and day

[Juan_Gutierrez]

I am a new AppSheet user (two days) and I require your support for the following:
In a table I keep the history and balances of the operations that I make, I am looking for being able to make the summarization per day of these operations to be able to consult later by date these amounts, but I am not finding how to do it.

My source file is excel.

Thank you very much for your support
