How do I freeze a value in Google Sheets?

Question:

( byraphaefeli)

Hello,

I'm creating a spreadsheet with costs related to Brazilian Reais and I need to freeze the day's exchange rate.
Right now I'm doing this:
1. =GoogleFinance("CURRENCY:USDBRL") - This gives me today's exchange rate. (2.30).2. Today, I want to divide an amount, for example, 100 by the exchange rate which gives me USD 43.47. 3. Let's say, tomorrow I divide another 100 but the exchange is 2.45, giving me USD 40.81.
I want to freeze these amounts so that I know how much I'm paying for an item based on a day's exchange rate and not have these amounts changed when the rate changes and so on... Does anyone know if this is possible?
Thanks!
Solution:

Have a look at the following animated screenshot:



I have the following formula in Cell A1:=GoogleFinance("CURRENCY:USDBRL")

And when I insert the following formula in Cell A4:
=GOOGLEFINANCE("CURRENCY:USDBRL")

The custom function "freeze()" will check if the formula has "=GOOGLEFINANCE" (that is all capital letters) then it will take the value of it and it will again put it back but it will remove the formula. So the value will be freezed.

Have a look at the following code:

///////////////////////////////////////

function onEdit(e) {
freeze();
}

function freeze() {
Utilities.sleep(1500);
var activeCell = SpreadsheetApp.getActiveSheet().getActiveCell();
var formula = activeCell.getFormula();
if( formula.slice( 0 , 14 - formula.length ) == "=GOOGLEFINANCE" ) {
 var temp = activeCell.getValue();
 activeCell.setValue(temp);
}

}

///////////////////////////////////////

put the above code in your script editor, and then you can use it directly in your Google Spreadsheet.
