Google Apps Script – How to Create Folders in Directories with DriveApp

Google Apps Script – DriveApp

Well, it’s  a rainy day here travelling in Romania, so time for a post.

coding in Romania
Relaxing in a cafe in Cluj Napoca, Romaina on a Rainy. I love this country!!!

When creating a Google Apps Script’s I often find I am creating new folders and files in specific locations on Google Drive after, say, generating a report or something.

A Note on Folders in Google Drive

All files and folders in Google Drive are allocated a unique key that identifies them.

Google Drive Folder ID

The file location and all the data about the file is mapped to this ID. This means you can have as many folders or files with the same name even in the same directory without a duplicate error being thrown because they all have their own unique ID for their URL.

Getting Started

More often than not, I know the parent folder that I want to put my sub folders in. This means I can get the parent folder’s ID and use that as my starting point to add sub folders. To do this we use the DriveApp class.

Below are three useful functions for creating folders.

  • Simple – Create a folder under the Parent folder ID – Duplicates are not checked and there can be multiple sub folders with the same name but all have their own  unique id.
  • Medium – Create a folder only if that folder name does not exists in the Parent folder – No folder is created if the folder already exists.
  • Hard-ish – Create a folder. If the name exists, add a counter to the name – If the file already exists then add a counter to the end of the file name.

All the functions will take two arguments: folderID – the unique id of the parent folder and folderName – the name you want to call your new folder.

The start() function will simply grab the two variables for the folderID and folderName and run the folder creation function. This is to simulate using the functions in your code.

Feel free to read what you need. I try and write these for a wide range of coding skill in mind.

Google Apps Script – Getting Input Data From a Dialog Box in Google Sheets

Google Apps Script, Jquery, Javascript, HTML

One of the weekly tasks in my day job as an academic administrator is to look at a number of ‘modules’ or courses that our college is running and complete some analysis and crosschecking. Each week the students complete a ‘unit’. However, during some quarters, not all modules are doing the same unit. Before I can run my code I need to determine what modules are running and what units we are up to for me to run my automated code.

To do this I created a dialog box when the code is run from the add-on bar. In a few clicks, I can then choose the relevant modules and units and then run the selected code.

Let’s take a look at what the dialog box looks like:

Dialog Form in Google Apps Script

Upon “Submit”, the dialog box returns an array  of objects of checked values from the radio buttons that can be uses in the server-side Google Apps Script.

In this tutorial we will look at the following :

Google Apps Script – How to Automatically Generate a Time From a Four Digit 24 hour Time in Google Sheets.

Google Apps Script, Google Sheets

On a recent board post a Google Sheets user wanted to change a four digit number (for example, 1230) to a time, like 12:30, in the same cell that the item was entered.

Unfortunately the user was not in a position to change the starting values, so they were left with the 4 digits.

There are two ways of doing this with varying levels of complexity:

 

  1. The Google Sheets Formula Approach
  2. The Google Apps Script onEdit Approach

How to Hide a Row based on a Cell Value in Google Sheets with Filter or Google Apps Script.

Google Sheets, Google Apps Script

Sometimes, when you are working on a shared Google Sheet you might want to hide a row based on a cell value.

For example, perhaps we don’t want to see row information of orders that have been paid for. Take a look at my D&D miniatures wholesale orders sheet (image below). I know I don’t need to follow up the orders that have been paid, marked with a ‘Yes’ in column F, so I don’t want to see them on my sheet.

We want to hide the "Yes" - Google Sheets

We can hide these two ways:

  1. Create a filter.
  2. Google Apps Script onEdit() trigger.

Sections to Sheets – Free Google Add-on That Separates Column Sections Into Individual Sheets for Page-by-Page Export or Printing

What is Sections to Sheets?

Sections to Sheets is a free Google Sheets Add-on that separates rows by column sections and puts them in individual pages or sheets in a spreadsheet in preparation export and printing.

You can find Sections to Sheets at the Google Chrome Webstore.

Chrome Web Store Badge

Example 1

Let’s say you want to print out a list of expenditures by department and you want each department to start on a new page. You’ll also want to keep the same header for each page.

Example 2

You might want to export a list of grades by class number. You sort the grades by class and then export the list with each class starting on a new page with a header and footer.

Sections to Sheets can help you achieve this quickly by creating a new Google Spreadsheet and separating each selection and putting it into a new Sheet(tab) with or without headers and footer. This will enable you to quickly export or print your sheets.

Google Apps Script – Copy and Paste Cells While Retaining Column Width in Google Sheets.

Google Apps Script

Have you ever copied and pasted something in Google Sheets only to be frustrated with the fact that it stubbornly refuses to paste the column widths? I mean, everything else is perfect, the formatting, the formulas the comments, they all were pasted across just fine. However, that dastardly column width just does not budge.

When you want to copy and paste this…
Paste without column widths.
…but you get this.

Google Apps Script – Disable Enable Submit Button in Sidebar

Google Apps Script, Javascript, Jquery, HTML

I was working on a Google Apps Script project lately in Google Sheets that set up parameters in a sidebar and then ran the process once the user clicked the “Submit” button. The problem was that the process was taking a while and that “Submit” Button was ripe to be clicked multiple times by the impatient user, before the server-side code could even finish it’s operation.

To fix this I needed to disable the submit button once it had been clicked and then enable it again once the server-side process was complete. Here, I need to:

  1. Disable the button and get the data from the client-side Javascript inside my sidebar’s html file.
  2. Do something awesome with it server-side.
  3. Upon the completion of the server-side awesome, call back to the html file and enable the button again.

The Example

I have a very simple Google Sheets Side Bar with a “Submit” and “Cancel” button. When the “Submit” button is clicked it calls the function submittington (can he get any more creative? No. No he can’t).

This function then disables the “Submit” button sends a variable to the client side code.gs and displays it stylishly in the sheet multiple times for the users viewing pleasure. After the code.gs function is executed, it calls back to the client-side submittington function and enables the button.

Behold!!! The example:

How do I download YouTube videos with Python 3 using Pytube?

Python 3, pytube 9.0.6 in Windows 10. 

pytube is a very easy to use, light-weight library that you can sue to download YouTube Videos.

Installation can be achieved in the terminal or command prompt with pip:

To download a video from YouTube you don’t really have to do much. So much so that you can get everything you need from the shell and be downloading a video in two lines of code.

In line 2 you can see that we have copied and pasted our YouTube url. You can either use the one in the Address Bar on the one that appears when you click “Share” on YouTube.

Skewed Random Range in Google Sheets (RANDBETWEEN)

The Standard RANDBETWEEN

We can achieve a random range of numbers in Google Sheets by using the RANDBETWEEN formula. The formula is quite simple to use. Just add your start range and your end range:

=RANDBETWEEN(start range, end range)

For example, if I want to get a random number between zero(o) and 60 I would do the following:

=RANDBETWEEN(0,60)

The result will provide a whole random number somewhere between these two and including these numbers.

If I were to repeat this formula over a reasonable sample, say 300 times, we should see a fairly even spread of numbers occurring a roughly the same frequency, just like in the graph below:

But what if we wanted to have fewer random numbers in our list at the lower or upper end or on both ends?

How do I Randomly Assign People to a Group Without Doubling Up on the Same Group in Google Sheets

Random Combinations Without Repetition Using Arrays, TRANSPOSE and Randomize Ranges

Say you have a list of  30 people and a 30 list of groups. After every half hour for six hours the people must change to another group, but they cannot go back to a group they have already been in.

How can we schedule 12 sessions where every person can randomly go to another group without going to the same group twice?

This is pretty much the same issue I face when scheduling my teachers to proctor exams randomly each quarter for different classes. The rules I need to follow are:

  1. No teacher should proctor the same class twice.
  2. Assignment to proctor a class should seem random.
  3. The teacher that teaches the class cannot proctor their own class.
  4. Each week has an exam over the term. The term runs for 8 weeks plus a final requiring a total of 9 proctor sessions.
