Looping through a google sheet to remove rows - Compare dates - google-apps-script

Question

The code needs to delete rows have a date before the current date. I'm not getting any syntax errors, but I think there is a semantic problem as the code will not change the spreadsheet in any way.
function checkDateValue(e) {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
var todaysDate = new Date().getDate();
var columnGCells = sheet.getRange("G2:G");
var columnG = columnGCells.getValues();
for (i = 1; i < sheet.height; i++) {
var endDate = new Date()
endDate = columnG[i];
if (todaysDate.getYear() >= endDate.getYear()){
if (todaysDate.getMonth() >= endDate.getMonth()){
if (todaysDate.getDay >= endDate.getDay()){
sheet.deleteRow(i);
}
}
}
}
};
checkDateValue();

Answer 1

The code would probably look something like this:
function checkDateValue(e) {
var colG_values,columnGCells,columnNumber,endDate,i,lastRow,
sheet,startRow,todaysDate;
startRow = 2;//Get data starting in this row
columnNumber = 7://The column number to get the data from
sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
lastRow = sheet.getLastRow();
todaysDate = new Date().getDate();
//Logger.log('todaysDate: ' + todaysDate);
columnGCells = sheet.getRange(startRow,columnNumber,lastRow-1,1);
colG_values = columnGCells.getValues();
for (i = lastRow; i > 1; i--) {//Loop through values from last to first-
//Need to stop at row one-
endDate = colG_values[i];
endDate = new Date(endDate);
if (todaysDate.getYear() >= endDate.getYear()){
if (todaysDate.getMonth() >= endDate.getMonth()){
if (todaysDate.getDay >= endDate.getDay()){
sheet.deleteRow(i);//Delete this row
}
}
}
};
};
function runTest() {
checkDateValue();
};
