Google Sheets: How to hide formula error warnings where there is no data or the data divides by zero

Google Sheets, IFERROR, ISBLANK, IF

Have you ever set up a Google Sheet with formulas that you drag all the way down to the bottom? See all those messy error values littering your otherwise immaculate spreadsheet when those formulas don’t reference a value? It sucks, right?

Formual errors referencing empty values Google Sheets

What if I told you that you could hide all those messy errors? What if I told you that you could truly have that pristine nirvana that you have been imagining that your Google Sheet project would truly be?

Drink the Kool-Aid and strap in, my friends, as your very own guru in a goat takes you on a journey of enlightenment into hiding formula error when:

Multiple Cell Data and Formula Reference With Find and Replace – Google Sheets

One of my biggest regrets when I first got started with Google Sheets and spreadsheets in general, was not taking full advantage of Find and Replace.

Find and Replace is the penicillin of the Spreadsheet world. It can rapidly cure all sorts or issue with a simple set of commands. It is seriously amazing stuff.

Yeah! Yeah! We all know about Find and Replace.

I know! I thought so too, but then I started to really use and identify how I could use it to quickly:

  • Change template sheets.
  • Fix bulk errors in formulas.
  • Change parts of cells.
  • Replace values in the whole spreadsheet, one sheet or a selected range.

Before we get started, you need to know the short cut for the Find and Replace tool. This will come in handy in all sorts of programs and apps.

  • PC – Ctrl + H
  • Mac – CMD (⌘) + H

I’m going to go ahead and continue the examples using PC, because, you know, Mac.

How do I reverse the Rows in A Column in Google Sheets? (Updated January 2022)

Google Sheets: SORT, INDEX, ROWS

Reverse Rows in Column in Google Sheets
My favourite Killjoy members. Column A – From most favourite. Column B Saving the best for last.

Sometimes you have a need to reverse a list quickly in Google Sheets.

That’s pretty easy to do if the list is sorted alphabetically. Just go on into the <Data> menu and choose from one of the sort functions. But what if the data you want to flip is not in alphabetical or numeric order?

Below are 3 ways to reverse your data:

For the examples below, I’ll be using a list of my favourite Killjoys characters. Yeah, I’m a sci-fi geek.

Skewed Random Range in Google Sheets (RANDBETWEEN)

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

Google Sheets: TRANSPOSE, arrays, Randomize Ranges

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.
