How to overwrite cell function with Paste value only using Google Script - google-apps-script

Question

I have a database that makes live calculations, but once the new data added to the database has been processed that day, I effectively want to Copy + Paste value only on these cells so that the results of the formulas are fixed and can no longer change.
The current script I am using is:
function myFunction() {
var sh = SpreadsheetApp.getActiveSpreadsheet();
var ss = sh.getActiveSheet();
var r = ss.getRange(1,2,ss.getLastRow());
var vals = r.getValues();
for(var i =0;i<vals.length;i++){
ss.getRange(i+1,2).setValue(ss.getRange(i+1,2).getValue());
}
}
However, in column B beneath the data set, all the cells start with IF(B2092="","",etc). On cells that are empty, I still require the formula to remain in place. I only want to script to be applied to cells that have data within.
Can anyone help with this? Thanks

Answer 1

Try this:
function myFunction() {
var sh = SpreadsheetApp.getActive();
var ss = sh.getActiveSheet();
var rg = ss.getRange(1,2,ss.getLastRow());
var vals = rg.getValues(); // get values
var formulas = rg.getFormulas(); // get formulas
// merge values & formulas
var data = formulas.map((row,row_index) =>
row.map((cel, cel_index) =>
{ return (cel) ? cel : vals[row_index][cel_index] }));
rg.setFormulas(data); // output
}
Corrected version:
function copy_values_and_formulas() {
var sh = SpreadsheetApp.getActive();
var ss = sh.getActiveSheet();
var rg = ss.getRange(1,2,ss.getLastRow());
var vals = rg.getValues(); // get values
var formulas = rg.getFormulas(); // get formulas
// merge values & formulas
var data = vals.map((row, row_index) =>
row.map((cel, cel_index) =>
{ return (cel == 0) ? formulas[row_index][cel_index] : cel }));
rg.setFormulas(data); // output
}

function myFunction() {
var sh = SpreadsheetApp.getActive();
var ss = sh.getActiveSheet();
var rg = ss.getRange(1,2,ss.getLastRow());
var vals = rg.getDisplayValues();
for(var i=0;i<vals.length;i++){
if(vals[i][1] && vals[i][1].length!=0) {
ss.getRange(i+1,2).setValue(ss.getRange(i+1,2).getValue());
}
}
}
