Delete a row in Google Spreadsheets if value of cell in said row is 0 or blank

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

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);
};
