plugins – Statiscal wordpress site using imported Excel tables

Hello and thank you to all who can share help.

I create a website containing many static table data from a game that I update daily.

I import the data and convert it into Excel tables, then I have to import Excel tables from the wordpress site. And here is my problem.
I want to import about 50,000 tables and once I have finished the html and css updates, just update them by simply importing the new Excel tables. I have reviewed WpDatatables and Tablepress but I am not convinced that they can handle the number of tables.
I've also looked at paid plugins like ipushpull and caspio, which seem a little exaggerated.
I am also open to the ideas that they will excel and directly convert the data.
Any help would be greatly appreciated.
