Question

I\'d like to be able to delete an entire row in a Google Spreadsheets if the value entered for say column \"C\" in that row is 0 or blank. Is there a simple script I could w

Answer 1

This simple code did the job for me!

    function myFunction() {

      var ss = SpreadsheetApp.getActiveSpreadsheet();  // get active spreadsheet

      var activeRow = ss.getActiveRange().getRowIndex();  // get active/selected row

var start=1;
var end=650;
var match='';
var match2=0;   //Edit this according to your choice.

     for (var i = start; i <= end; i++) {
      var columnC = ss.getRange("C"+i).getValue();
      if (columnC ==match  || columnC ==match2){ ss.deleteRow(i); }
     }
    }

This is what I managed to make work. You can see that I looped backwards through the sheet so that as a row was deleted the next row wouldn't be skipped. I hope this helps somebody.

  function UpdateLog() {

  var returnSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('RetLog');
  var rowCount = returnSheet.getLastRow();

  for (i = rowCount; i > 0; i--) {
    var rrCell = 'G' + i;
    var cell = returnSheet.getRange(rrCell).getValue();
    if (cell > 0 ){
      logSheet.
      returnSheet.deleteRow(i);
    }
  }
}

There is a simpler way:

1. Use filtering to only show the rows which you want to delete. For example, my column based on which I want to delete rows had categories on them, A, B, C. Through the filtering interface I selected only A and B, which I wanted to delete.
2. Select all rows and delete them. Doing this, in my example, effectively selected all A and B rows and deleted them; now my spreadsheet does not show any rows.
3. Turn off the filter. This unhides my C rows. Done!

Answer 4

I wrote this script to do the same thing for one of my Google spreadsheets. I wanted to be able to run the script after all the data was in the spreadsheet so I have the script adding a menu option to run the script.

/**
 * Deletes rows in the active spreadsheet that contain 0 or
 * a blank valuein column "C". 
 * For more information on using the Spreadsheet API, see
 * https://developers.google.com/apps-script/service_spreadsheet
 */
function readRows() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var rows = sheet.getDataRange();
  var numRows = rows.getNumRows();
  var values = rows.getValues();

  var rowsDeleted = 0;
  for (var i = 0; i <= numRows - 1; i++) {
    var row = values[i];
    if (row[2] == 0 || row[2] == '') {
      sheet.deleteRow((parseInt(i)+1) - rowsDeleted);
      rowsDeleted++;
    }
  }
};

/**
 * Adds a custom menu to the active spreadsheet, containing a single menu item
 * for invoking the readRows() function specified above.
 * The onOpen() function, when defined, is automatically invoked whenever the
 * spreadsheet is opened.
 * For more information on using the Spreadsheet API, see
 * https://developers.google.com/apps-script/service_spreadsheet
 */
function onOpen() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet();
  var entries = [{
    name : "Remove rows where column C is 0 or blank",
    functionName : "readRows"
  }];
  sheet.addMenu("Script Center Menu", entries);
};
