Add Indent / Outdent Functionality to Google Spreadsheets

This tutorial demonstrates how to add an "Indent Text" menu item to a Google spreadsheet so you can indent/outdent text.

  • When the "Indent Text" menu item is selected, any cells within a single column selection will be indented by 5 spaces.

  • You can increase or decrease the number of spaces the text is indented by changing the line below so that the "5" is changed to a larger or smaller number (depending on your preference):

newValues.push(['=CONCAT(REPT( CHAR( 160 ), 5),"' + values[i][0] + '")']);
  • This code works on multiple cells so you can select an entire column and indent in bulk.
  1. Open your spreadsheet and select menu item "Tools" --> "Script Editor" step 1

  2. Once the script editor opens, copy and paste the code into the "Code.gs" file, beneath the code that's already included. step 2

  3. Go to menu "File" --> "Save" step 3

  4. Return to your spreadsheet and reload the browser. You may get a pop-up asking you to grant access to your new script - approve it. Once granted access, you should now see a new menu item called "Indent Text" to the right of the "Help" menu. Yay! indenting

var ss = SpreadsheetApp.getActiveSpreadsheet();
function moveText(direction) {
var values = ss.getActiveRange().getValues();
var cols = ss.getActiveRange().getNumColumns();
var rows = ss.getActiveRange().getNumRows();
var newValues = new Array();
for (x = 1; x <= rows; x++) {
for (y = 1; y <= cols; y++) {
var cell = ss.getActiveRange().getCell(x, y);
var value = cell.getValue();
var formula = (direction == ">>>") ? '=CONCAT(REPT( CHAR( 160 ), 5),"' + value + '")'
: '=IF(TRIM(LEFT("' + value + '", 5))=CONCAT(REPT( CHAR( 160 ), 5),""), MID("' + value + '", 6, LEN("' + value + '")), TRIM("' + value + '"))';
if (value != '') {
cell.setFormula([formula]);
cell.setValue(cell.getValue());
} else {
cell.setValue(['']);
}
}
}
};
function indentText() {
moveText(">>>");
};
function flushLeft() {
moveText("<<<");
};

var sheet = SpreadsheetApp.getActiveSpreadsheet();
var entries = [{
name : ">>>",
functionName : "indentText"

Hi @quesyrahsarah,

A few notes:

  • The previous code that I provided was just one function that needed to be replaced among the other functions. This enables the "Indent Text" menu in the spreadsheet editor. (Select cells, then use that menu to indent)
  • The previous code was not designed to be run directly from the code editor. However I did notice that error you noticed would also come up when removing indents if any of the selected cells didn't have indents, so I have fixed that in the example below.
  • The previous code would only add or remove the first indent in the cell, not considering newlines. The new code below will indent multiple lines.
  • This time I included the entire code so you should be able to replace what you have entirely. After saving, you may need to reload your spreadsheet or manually run the onOpen function from the code editor. I put this together quickly, so it might be buggy - please let me know if there are issues.
var ss = SpreadsheetApp.getActiveSpreadsheet();

function moveText(direction) {
  var indent = '     ';
  var range = ss.getActiveRange()
  var values = range.getValues();
  var newValues = [];

  for (rowI = 0; rowI < values.length; rowI++) {
    var row = values[rowI];
    newValues.push([]);
    for (colI = 0; colI < row.length; colI++) {
      var value = row[colI];

      if (direction == '>>>') {
        // Add indent(s)
        var strings = value.split("\n");
        var newStrings = [];
        for (stringI = 0; stringI < strings.length; stringI++) {
          var prefix = stringI === 0 ? "" : "\n";
          newStrings.push(prefix + indent + strings[stringI]);
        }
        newValues[rowI].push(newStrings.join(""));
      } else {
        // Remove indent(s)
        var strings = value.split("\n");
        var newStrings = [];
        for (stringI = 0; stringI < strings.length; stringI++) {
          var prefix = stringI === 0 ? "" : "\n";
          if (strings[stringI].indexOf(indent) == 0) {
            newStrings.push(prefix + strings[stringI].substr(5));
          } else {
            newStrings.push(prefix + strings[stringI]);
          }
        }
        newValues[rowI].push(newStrings.join(""));
      }
    }
  }
  
  range.setValues(newValues);
};

function indentText() {
  moveText(">>>");
};

function flushLeft() {
  moveText("<<<");

};

function onOpen() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet();

  var entries = [{
    name : ">>>",
    functionName : "indentText"
  },{
    name : "<<<",
    functionName : "flushLeft"

  }];
  sheet.addMenu("Indent Text", entries);
};

This works really nice. Thanks to all.
Is there a way to get it to modify the format but not the content of the cell? (similar to the " @" custom formating)
