Google Apps Script – When I add a value to a cell in a selected column, I want it to move to another Google Sheet

Google Apps Script: onEdit, Google Sheets

Sometimes you want to be able to automatically move a row from one sheet to another based on the value of a certain cell.

The Example

One of the first things that come to mind, and I am sure it does for you dear reader, is when I took advantage of the Great Chicken Transformation back in, oh, 2019, I believe.

Folk kept turning into chickens, while other folk were wanting eggs. It just so happened that I had the farm to make it all happen.

First, though, I needed to keep a tab of every person I knew and if they turned into a chicken. If they did, then they were destined for the pen.

…Note to self: it may be late at night, but dam Yagi, your analogies are tight!

Google Sheets and Google Apps Script to the rescue.

So first off I set up a sheet named: Plague. Here I put all the people I knew, so I could watch em good and propper.

Next, I set up a sheet named Farm. These are for the people who turned into chickens. No harm in profiting from a few newly formed egg layers, right?

Whenever a new transformation occurs, I find the person on the Plague sheet and then select “Yes”  to say that they have turned into a chicken and will now be spending their days on the farm. Upon editing (onEdit) this cell to “Yes”, the row is copied and pasted to the Farm sheet.

Just like this:

Google Apps Script – Create Custom Unique IDs in Google Sheets

Google Apps Script, Google Sheet

Sometimes something on the surface that sounds downright easy turns out to be quite a complex procedure. My recent experience in creating a Custom Unique ID in Google Sheets using Google Apps Script was a case in point.

In a previous version, I created a simple unique ID generator by taking advantage of JavaScript’s Date object.  It was a mere 41 lines of code. You can take a look at it here:

Google Apps Script – Adding a Unique ID in a Cell on Edit of an Adjacent Cell Using Time

Then curiosity got the better of me, and I wanted to know how to create a custom ID generator. My requirements were simple:

  • It needs to be able to take any size number format. For example, from 1003 to 100000000000003.
  • It needs to handle leading zeroes. For example 0000653.
  • It needs to be able to take optional leading and trailing letters. For example, AR1340203, 3000484030BSTN, ENT900848933IRE.
  • It needs to generate a unique ID based on the pattern provided by at least one ID in the ID Column of the Sheet.
  • It needs to be able to look through all the unsorted IDs in the ID column and find the next largest number that will become the new ID.
  • It needs to be able to create IDs on multiple sheets.
  • It needs to be customisable and easily reusable in other projects.

For this project, the code would not handle the following:

  • It won’t handle letters between numbers. For example, ERC1299374ER3900TT.
  • It won’t handle non-alphanumeric characters. For example, 13948%$&)
  • ID’s must be of the same length and the newly created ID must have the same length of characters as the previous ones. For example, A99C >>  A100C.

The Results

After an afternoon tinkering, the results turned out pretty good. Take a look at the demo below:

Google Apps Script – Adding a Unique ID in a Cell on Edit of an Adjacent Cell Using Time

Google Apps Script, onEdit, Date, Google Sheets

Here is the scenario. You have a small business and you want to store your customers, products and sales information on separate Google sheets.

You’re probably going to have someone from your staff enter new customers, products are sales transactions.

We know if we get them to enter unique ID’s in manually that mistakes are going to get made. So how about we automate this process with unique ID’s based on date-timestamps.

uniqueID DateTimestamp Google Sheets

Why use a date-timestamp to create a unique ID?

Every year is unique. Every day, hour, minute, second and millisecond of that year creates a unique number. This mean that a new unique id will be create every millisecond for us.

Wow! Wow! Wow! Yagi! Just hold it one damn minute! You could  have multiple results each millisecond that would each be the same number!

Well, true if we were running a loop generating and publishnig our date-timestamp, we could have multiple numbers. However, we are generating this unique ID as an onEdit function when the user adds some information in Google Sheets to a cell and an adjacent cell  returns our unique number.

The user’s input and then the calls to and from the server to the Google Sheet will be sufficiently slow enough not to have a number generated multiple times a millisecond, so we are safe there.

We have the main idea of what we are planning, let’s move onto the example.

Google Apps Script – How to Get the Sheet Name and Spreadsheet Name and add to a Cell on Google Sheets with a Custom Function

Google Apps Script, Custom Functions

Boy, are these titles getting longer. 

But that’s pretty much the gist of it. In this post we will look at creating a Google Apps Script Custom Function that allows you to do Three things in Google Sheets: 

  1. Get the current sheet name.  That’s the same sheet name as the cell you are working in.
  2. Get all the sheet names. A full list of all the sheet names. 
  3. Get the name of the Spreadsheet file. 
Get Sheet Names and Spreadsheet Names Only - Google Apps Script

The above picture is pretty self-explanatory. If you type in:

=SHEETNAME(#)

Where “#”  is a number 0, 1 or 2 you will get the results displayed in the picture. Any other number will display an error.

Google Apps Script – Copy Selected Columns in One Sheet and Add Them To The Bottom of Different Selected Columns in Another

I recently had a legend (a.k.a reader) ask about how to copy selected columns from one sheet and append them to the bottom of different selected columns in another sheet. 

To me, this seemed like a pretty common task that one might face, so in response, I decided to create a template function to easily do this and reuse on the same project or in other projects. 

But first, let’s take a look a the problem a bit more. 

We want:

  1. the freedom to select any number of columns from one sheet.
  2. to select the same number of different columns from the sheet we want to paste to.
  3. to paste to the bottom (append) the receiving sheet.
  4. to take into account varying header row heights.
  5. to have a “Completed” or “Copied” column in our origin sheet so that we don’t continue to paste all the data instead of simply what has been updated.
  6. have the data with formulas that we only want to paste the values for.

The Example

Let’s say we have a sheet that is updated regularly and we want to be able to paste data from columns A, B and C of this source sheet and append it to columns C, E and A of the destination Sheet. 

  • Copy Sheet 1 Col A -> Append Sheet 2 Col C
  • Copy Sheet 1 Col B -> Append Sheet 2 Col E
  • Copy Sheet 1 Col C -> Append Sheet 2 Col A

Take a look at our two Google Sheets 

SourceSheet - Google Sheets
DestinationSheet - Google Sheets

You can see in the Source Sheet (Sheet1) that we have 3 data columns and one column market To Copy. The To Copy column will be updated with “Copied” once the code is run successfully.

In the Destination Sheet (Sheet2) you can see that we already have some data there. We don’t want to overwrite it. We simply want to append our data to the bottom of it.

Google Apps Script – How to Change the File Name of Non-Native Files like MS Word Docs, PDF’s and Excel files.

Google Apps Script, DriveApp

I had an unexpected need to change some non-native file names – in my case, MS Word docs – to something else to appease my masters. Being the resident Igor, I delighted in the task. 

The Problem

I had a folder of MS Word documents on my Google Drive that needed to all be renamed. They all needed the same name with an index number to distinguish that they were different files. 

There were however other file types in the folder. 

The problem with non-native files in Google Drive is that it’s a little tricky to find their ID. Besides, I just wanted to change ALL files that were MS Word in the folder. 

What I would need to do is search for all files inside my selected folder that are of MS Word type and rename them with the same name but with a counter at the end. For example:

Old File Name New File Name
boring.doc cranberrySauce.doc
sad.doc cranberrySauce1.doc
yawn.doc cranberrySauce2.doc
