Transferring numerous Excel data to an online database

[Dolphin]

Hello, we enter thousands of data points separated by weeks, including sales, stock, store names, etc., into Excel and create summaries using pivot tables. While processing this data in Office for Mac, it lags. In addition, when a certain number of rows is exceeded (I think 1 million), Excel does not allow for adding more rows. How can we create a web-based system that is easy to use and does not burden us? Is it possible to manage this type of database without coding knowledge? I kindly request your assistance. Thank you.
