How do I add an spreadsheet to a game?

I am making a game which involves a spreadsheet I did in excel.

I just want to know how could I incorporate the spreadsheet and show certain cells of it in text box's and also add and subtract from the spreadsheet while playing the game?

Basically a general database which can constantly be updated through the game.

Cheers

Probably the simplest is to export the spreadsheet as an array in JSON, and if you need to change it, store it in LocalStorage
