This probably seems like a dumb question. In fact, everyone I’ve asked this to thinks this is a dumb question. This might seem even dumber given that I’m a professional tutor, and I’ve taught literally thousands of students in classrooms and online.

But before the entire world yells at me, let me start off with an anecdote, as these sorts of essays tend to start. In their last few years of high school, my brothers had a wonderful calculus teacher, Mrs. D. She was kind, warm, and taught them a lot about math. …

I’m a test-prep tutor for graduate exams, and I’m a good one. Still, some people do poorly with me. Their score remains flat, even after working hard. This is a post about the last group of people.

First, about me (and a little bit of bragging): I’m a test-prep tutor for graduate exams. I have hundreds of satisfied clients, many 5 star reviews, and my salary as a tutor is above the mean, for whatever that’s worth. Most people do well with me, and get the score they want. Some people do very well with me, and get a score that’s better than they could have dreamed.

But, if you’d rather not download it, here’s how to remove spaces in Google Sheets without Paperpusher.

I now present to you one of the most frustrating errors when comparing values in Google Sheets:

Are they going to the party? #N/A, YES

People: Jeff , Diane

People who have responded yes: Jeff, Diane

I’m certain I have my whole table set up perfectly. …

This blog post shows how to split cells and columns if you don’t want to download the add-on.

When I copy-paste tables from one format to a spreadsheet, I often find myself with cells and columns that I need to split together. Usually, Google Sheets is pretty good about handling this. …


The following is taken from PositSum’s blog. The easiest way to combine cells, rows, and columns in Google Sheets with custom separators is to use my free Google Sheets add-on, Paperpusher, which provides an easy way to combine rows and columns, split rows and columns, and correct other common OCR transcription and data entry errors and typos. However, if you’d rather not use Paperpusher, this series shows how to correct these errors using Google Sheets’ built-in functions.

Combining rows, columns, and cells in Google Sheets is actually an easy process. However, it can be frustrating before you figure it out.


The following is taken from PositSum’s blog. Also, the easiest way of converting letters to numbers, commas to periods, numbers to letters, and other common OCR transcription and data entry errors is to use my free Google Sheets add-on, Paperpusher. However, if you’d rather do it manually, here’s how you do it below.
