I have a google sheet that I use to keep track of my spending. I create a new 'block' of data every time I get paid, and I have formulas in some of the cells that calculate balances.
I have data that goes back over a year, that I'm no longer interested in calculating any more. Once Google Sheets loads my page, is there an easy way to change the value in a cell to the value that is actually there, as opposed to the formula? That way, it doesn't take my page so long to load calculating values that aren't going to be changing any more?
