I am trying to set the value of a cell in a column when two other columns at an index match values. How can I set the value using an index? (<Edited)
for (let i = 0; i < assetId.length; i ) {
for (let p = 0; p < oldId.length; p ) {
if (assetId[i] !="" && oldId[p] !="") {
if (assetId[i] == oldId[p]) {
Logger.log('Old Match: ' assetId[i])
//if match modify 4th column at row [i] to 'null'
d.getRange(i,3).setValue('null')
}
}
}
}
Based on if assetId[i] == oldId[p], I am trying to change column F of row [i] to 'null'
Column J is oldId and K is newId
EXPECTED OUTPUT: F4 should be null
Full code:
function replaceIds() {
const ss = SpreadsheetApp.getActiveSpreadsheet()
const r = ss.getSheetByName("Form Responses 1")
const d = ss.getSheetByName("Devices")
const oldId = r.getRange("J2:J").getValues().flat()
const newId = r.getRange("K2:K").getValues().flat()
const studentName = r.getRange("C2:C").getValues().flat()
const assetId = d.getRange("G3:G").getValues().flat()
const annotatedUser = d.getRange("E3:E").getValues().flat()
for (let i = 0; i < assetId.length; i ) {
for (let p = 0; p < oldId.length; p ) {
if (assetId[i] !="" && oldId[p] !="") {
if (assetId[i] == oldId[p]) {
Logger.log('Old Match: ' assetId[i])
//if match modify 4th column at row [i] to 'null'
d.getRange(i,3).setValue('null')
}
}
}
//new asset ID loop
for (let r = 0; r < newId.length; r ) {
//Logger.log(oldId[p])
if (assetId[i] !="") {
if (newId[r] !="") {
//Logger.log('## not null ##')
if (assetId[i] == newId[r]) {
Logger.log('New Match: ' assetId[i])
}
}
}
}
}
}

Issue:
- Issue is that, using a nested
for
loop is not a good idea as you can't properly follow where the proper index is, and it will also needlessly reiterate on items that were already visited.
Solution:
- Looping only on the
assetId
should suffice, then usingindexOf
as it will help you identify if a certain element (currentassetId
) belongs in an array (list ofoldId
s). - If
assetId
is found,indexOf
will return a non-negative number (which is what index the element is found in the array). - Exclude empty
assetId
s due to how you get your data - Then you can remove the column of that same row, but since
index
starts at 0 and your data starts at 3rd row, we need to offset thegetRange
row so it would match the cell we want to delete properly.
Modifying your current solution, this is what the solution says above, and should work.
Script:
function replaceIds() {
const ss = SpreadsheetApp.getActiveSpreadsheet()
const r = ss.getSheetByName("Form Responses 1")
const d = ss.getSheetByName("Devices")
const oldId = r.getRange("J2:J").getValues().flat()
const newId = r.getRange("K2:K").getValues().flat()
const studentName = r.getRange("C2:C").getValues().flat()
const assetId = d.getRange("G3:G").getValues().flat()
const annotatedUser = d.getRange("E3:E").getValues().flat()
// loop your assetId
assetId.forEach(function(cell, index){
// if assetId is listed under oldId, remove annotated location of that row
// also, skip any rows where assetIds are blank
if(oldId.indexOf(cell) > -1 && cell != "")
// offset here is 3 since assetId starts at G3 and index starts at 0
// 3 - 0 = 3, which is the offset, and 6 is column F
d.getRange(index 3, 6).setValue('');
});
}

This function will change the value in column1 if the value of col2 at that index is in column 10 on any line. you can change the indices as you desire.
function findDataBasedOnMatch() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Sheet0');
const sr = 2;//data start row
const vs = sh.getRange(sr, 1, sh.getLastRow() - sr 1, sh.getLastColumn()).getValues();
const col10 =vs.map(r => r[9]);//you pick the indices
vs.forEach((r,i) => {
if(~col10.indexOf(r[1])) {//you pick the indices
sh.getRange(i sr, 1).setValue('');
}
});
