Hi Marnick,
I would advice you to split your Excel sheets, each for every single calculator, just for a performance reason.
Large Excel files take more time to be calculated and your customers could not like it.
But if you would like to take this way you could Just use the base price to identify the different calculator but you have to give up the “base price” for these products:
1) Set a different price for each of your WooCommerce products which you wish to be included in your calculators.
2) create your calculator uploading your spreadsheet file and map the “Base Price” with one of your field.
3) Use this field to recognize the calculator/formulas (For example: Base Price = 1, Formula 1 | Base Price = 2, Formula 2 and so on)
4) Remember to assign the products in your calculator.
If you don’t like to give up the base price I have another solution, but it’s a more complicated solution.
Kind regards,
Enrico
