    <p>Your specific question was:</p> <blockquote> <p>My question: Is it possible for the script to know the A1notation of the 1st occurrence of a value and add a row above it?</p> </blockquote> <p>By using a combination of a Boolean to indicate whether you've found <em>any</em> of the items you are looking for, and a couple of <code>Range</code> methods, you can get the A1notation of the first occurrence. </p> <pre><code>var column = 1; // this example is only using column A var foundGerman = false; var firstGerman = ''; ... if (lang[i] == 'German') { if (!foundGerman) { foundGerman = true; firstGerman = range.getCell(i, column).getA1Notation(); } ... } </code></pre> <p>After that, you will have the A1Notation of the first cell containing "German".</p> <p>However, the function <code>insertRowsBefore()</code> is a <code>Sheet</code> method, and expects a row number as a parameter, not A1Notation. So figuring out what the address of the first German cell was turns out to be unnecessary. </p> <h2>Script</h2> <p>Here's my entry in the contest! For speed, it's wise to use as few apps script service calls as possible. In this script, all data manipulation is done using arrays, with the final result written once. </p> <p>In anticipation that you'll have more than three languages that you care about, and for maintainability, the language lookup is handled by an Object, <code>iso639</code>. (Assuming you're using <a href="http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes" rel="nofollow">ISO 639-1 Language Codes</a>.) As a result, the actual work takes just 10 lines of code!</p> <pre><code>function insertViaArray() { var sheet = SpreadsheetApp.getActive().getSheetByName('REPORT'); var values = sheet.getDataRange().getValues(); var newValues = []; var iso639 = { "German" : "DE", "Italian" : "IT", "French" : "FR" } var curLang = ''; for (var i in values) { if (values[i][0] !== curLang) { curLang = values[i][0]; newValues.push([iso639[curLang]]); } newValues.push([values[i][0]]); } sheet.getRange(1, 1, newValues.length, 1).setValues(newValues) }; </code></pre> <p><strong>Edit</strong> Script V2</p> <p>By using <code>Array.splice()</code> to insert the language tags, we can further reduce the code to 8 working lines, and eliminate the need for a parallel <code>newValues</code> array.</p> <pre><code>function insertViaArrayV2() { var sheet = SpreadsheetApp.getActive().getSheetByName('REPORT'); var values = sheet.getDataRange().getValues(); var iso639 = { "German" : "DE", "Italian" : "IT", "French" : "FR" } var curLang = ''; for (var i = 0; i &lt; values.length; i++) { if (values[i][0] !== curLang) { curLang = values[i][0]; values.splice(i, 0, [iso639[curLang]]); } } sheet.getRange(1, 1, values.length, 1).setValues(values) }; </code></pre>

    1. CO*Here's my entry in the contest!* ... and the winner is... Mogsdad ! for this iso trick and compactness! just a note : I didn't take the array solution because I was thinking that there are probably more data on this sheet and/or some formatting... that's why I kept the api calls in the loop. Anyway, +1 for aforementioned reason ;)

    3. COIf I was wearing a top hat I would tip it to you @Mogsdad Good thing that the data will always be ordered alphabetically otherwise it would be a nightmare! I have tried your solution and is it correct in assuming it re-arranges the data rather than adding a row above the first instance?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
