Organise Google Drive files into a JavaScript object for use with Google Apps Script

Organise Google Drive files into a JavaScript Object so that they can be looped through for each named individual.

Files to loop through and organise

Files to loop through and organise

The following Google Apps Script is designed to go through a folder of Google Drive files where a number of tutors have individual files for groups of students they teach. The code will collate all of the relevant files (specifically their IDs) that belong to each tutor, so that at a later date we can loop through the organised data set and create individual Google Sheets for each tutor and compile their student data into it.

What this code ultimately allows us to achieve is the ability to go through the files and get them organised for further coding.

In this example we have a file name pattern of ModuleCode – Tutor Name – Group Number for example ABC – Jane Doe – Grp 02. So we want to collate all of the files that belong to Jane Doe first, then move on to the next tutor (Micky Mouse in this example).

The collated data will look like this:

{
   "Jane Doe":[
      "FILE ID HERE",
      "FILE ID HERE",
      "FILE ID HERE"
   ],
   "Micky Mouse":[
      "FILE ID HERE",
      "FILE ID HERE"
   ]
}

Merging multiple PDF files as a single PDF and converting all the pages in a PDF to PNG images using Google Apps Script

This is a sample script for merging multiple PDF files as a single PDF file using Google Apps Script. [and] This is a sample script for converting all pages in a PDF file to PNG images using Google Apps Script.

Kanshi Tanaike has recently been exploring and sharing some Apps Script solutions for handling PDF Documents using the PDF-LIB JavaScript library. So far they have looked at merging PDF files as well as converting PDF pages into PNG images.

The solution uses fetch and eval to load PDF-LIB, but with a minor modification hoisting the declaration of setTimeout you can also copy the source code into the script editor and avoid the evils of evals (a modified example here).

The Apps Script execution runtime limit will be a factor in the size of PDF Documents you can handle, but for smaller jobs a great solution to keep in mind.

Google Apps Script Tip: Sorting through an array of duplicates

Sort through an array of duplicates and extract unique values into a new array.

Remove array duplicates

Remove array duplicates

The following Google Apps Script is designed to go through an array of values that contains duplicates and create a new array of only the unique ones, arranged alphabetically. I needed this code when looping through files in a Google Drive folder where tutors and their groups formed part of the filename that I needed to extract for the end file that was created.

Filter a try/catch error message when coding with Google Apps Script

Search a try/catch error message for keywords to determine the error message to log using JavaScript match.

Filter an error message in a try/catch

Filter an error message in a try/catch

The following Google Apps Script is designed to exercise how you might go about searching the error message in a ‘try/catch’ for keywords. I wanted this specifically for a tool I built that contains a lot of code (and hence a lot of potential error messages) between a try/catch, for which a very small number of people were experiencing a timezone issue with their Google Sheet file.

The aim was to use a JavaScript ‘match’ to find the keyword timezone and display a set of instructions for the user to resolve the issue themselves instead of just a generic error message.

Workaround: Checking Existence of File ID in Google Drive without Access token and API key using Google Apps Script

This is a workaround for checking the existence of file ID in Google Drive without both the access token and API key.

When you want to check whether the file of the file ID is existing in Google Drive, generally, you might use Drive API and Drive service (DriveApp) of Google Apps Script. In this case, the scope of Drive API is required to be used. By this, the access token and the API key (in the case of publicly shared files) are required to be used. But, there might be a case that the available scopes are limited. In this post, I would like to introduce a workaround for checking the existence of file ID in Google Drive without both the access token and API key.

This workaround could have been a nice addition to a recent project I was working on to audit a bunch of Google Drive file IDs. As noted in this post a big benefit of the approach is there is no need to include Google Drive authentication scopes to your project. See the source post for the code and explanation.

Reading Qualtrics survey details with Google Apps Script

Use the Qualtrics API to connect with a Survey and get its details.

Qualtrics API Survey details

Qualtrics API Survey details

Most of the complexity with this simply comes in getting the correct syntax for connecting to the Qualtrics API. This Get Survey Qualtrics webpage provides a little bit more technical detail for what exactly is sent/received.

You will need to complete the 3 pieces of information at the top of the Apps Script code for your own setup:

  1. API Token from the Qualtrics website,
  2. ID of the Survey you want the details of,
  3. Your Data Center ID.

Search Google Drive ‘Shared with me’ and collate the results

It will collate the following information into a Google Sheet:

  • The file name as a direct clickable link,
  • The file ID,
  • The type of file eg PDF, Google Sheet/Doc,
  • The file creation date,
  • The file last updated date,
  • The folder path,
  • The file owner.

Autofill Google Sheet Formula with Google Apps Script

Use Google Apps Script to Autofill a formula down rows in a Google Sheet.

Autofill Google Sheet Formula

Autofill Google Sheet Formula

The following Google Apps Script is designed to insert a formula into the first row of data in a Google Sheet, then use Autofill to add the formula to the subsequent rows below. In this example I am just using a simple Sum formula to add up age and shoesize for demo purposes. The need to do this came about when combining multiple Google Sheet files however, that needed calculations adding to the final composed version.
