openByURL opens first value and arrays down selected column - google-apps-script

Question

This will only open F2 and will array that value down column G...help?
function CountData() {
var sheet = SpreadsheetApp;
var urlsheet = sheet.getActiveSpreadsheet().getSheetByName('Sheet1');
var url = urlsheet.getRange('F2:F100').getValues();
for(var i=0;i<url.length;++i){
var formsheet = sheet.openByUrl(url);
var CountRows = formsheet.getActiveSheet().getLastRow();
urlsheet.getRange('G2:G').setValue(CountRows);
}
};

Answer 1

You're looping through the array, but you're not using the actual value. Keep in mind that .getValues() returns a 2-dimensional array, so you need to access the value using [i][0].
function CountData() {
var sheet = SpreadsheetApp;
var urlsheet = sheet.getActiveSpreadsheet().getSheetByName('Sheet1');
var urls = urlsheet.getRange('F2:F100').getValues(); // Renamed to be plural, indicating some kind of list
for(var i=0;i<urls.length;++i){
var formsheet = sheet.openByUrl(urls[i][0]); // Select the URL
// ... the rest of your code
}
};
I think the rest of the code in your for-loop will have issues because
The script is not container-bound to formsheet, so you can't access .getActiveSheet(). Try something like .getSheetByName() instead.
You're not updating the range urlsheet.getRange('G2:G'), so you're going to be replacing the values in that column for every url.

Answer 2

function CountData() {
var ush=SpreadsheetApp.getActive().getSheetByName('Sheet1');
var uv=ush.getRange(2,6,99,1).getValues().map(function(r){return r[0];});
var rA=[];
uv.forEach(function(url){rA.push([SpreadsheetApp.openByUrl(url).getActiveSheet().getLastRow()])});
ush.getRange(2,7,rA.length,rA[0].length).setValues(rA);
}
