No, there’s no equivalent to Excel’s EVALUATE()
in Google Sheets.
There’s long history behind this one, see this old post for instance.
If you’re just interested in simple math (as shown in your question), that can be done easily with a custom function.
function doMath( formula ) {
// Strip leading "=" if there
if (formula.charAt(0) === '=') formula = formula.substring(1);
return eval(formula)
}
For example, with your A1, put =doMath(A1)
in another cell, and it will be 3
.
