How to Fix My Wi-Fi at Work

There was a time, early in my career, when I opened a Microsoft Excel spreadsheet and just stared at it as if it were a foreign language. The grids, colors, and numbers seemed to flow in every direction, which felt intimidating. I was much more of a people person than a numbers person back then, and I thought Excel was something you only used when you wanted a headache.

I’ve learned to embrace Excel since then, picking up numerous useful tips and tricks to get the most out of the program. If, like me, you’re primarily self-taught, there are probably parts of the program you never knew existed, like what to do if someone asks you to pull prices or employee IDs across different sheets. Let me tell you, there’s a better way than manually copying and pasting, and it isn’t sorcery; let’s talk about VLOOKUP and XLOOKUP and see how much easier it can make your life.

Before We Dive In: Lookup vs VLOOKUP

When people talk about doing a lookup in Excel, they’re talking about the broader idea of finding a value in one place and returning related information from another. The concept itself isn’t tied to a specific tool; it’s just the mental model of “Find this. Give me that.” Think of your spreadsheet like a big filing cabinet with drawers and folders. A lookup is like asking, “Hey, I have this file label. Can you go find the matching folder and pull out the document I need?” Basically, it’s a search task.

Now, VLOOKUP is one of the old tools Excel gave us for doing that search. It works, but it has rules about how your data must be arranged, such as requiring that your filing cabinet have all labels on the left side of every drawer. If you don’t follow the rule exactly, VLOOKUP will complain or, worse, give you the wrong information.

By contrast, XLOOKUP is the newer tool that says, “Put your files wherever you want, and I’ll find them for you.” It’s modern, more flexible, and usually easier for beginners because it doesn’t demand your data live in a specific pattern. So when I say “lookup” in this blog, think of it as the task you want done. VLOOKUP and XLOOKUP are just two different tools for that task, with XLOOKUP being the one I generally recommend.

Now that we have the basic concepts, let’s walk through each of these tools as if we were sitting at the computer together.

Why Lookups Matter

Let’s be honest, the real reason lookups matter for most small business teams is because you already spend too much time re-entering the same customer details, troubleshooting mistakes, or hunting in the wrong sheet for contact info. That’s not spreadsheet work, it’s just busy work.

Now, we all know that businesses and organizations maintain several common lists, but we will focus on two for our examples. The first is a Customer Directory, the official list of all customers, including their Customer ID, name, email, and phone number; it’s the list that your sales, support, or admin teams reference constantly. The other is a Service Log, where someone records every support ticket, follow-up call, or scheduled outreach; in that log, you record the Customer ID and a note about the interaction.

The problem teams run into every day is that when you want to email a customer from the service log, you have to switch back to the directory, find the ID, and then copy the email. That’s the headache that lookups fix. A lookup function tells Excel which customer ID appears in the service log, then finds that same ID in the directory and returns the corresponding email or phone number automatically. You see, instead of manual searching, Excel does the lookup for you, because lookups are a simple way to connect one table to another based on a shared identifier. It lets you get data populated automatically, consistently, and without retyping anything.

Let’s walk through the lookups together to see how they work.

VLOOKUP: Pulling Customer Info the Traditional Way

To make this concrete, here’s a simple example your team could face where you have a sheet called Customer Directory that looks like this:

And then another sheet called Service Log:

All you have in the service log is the ID and the date, but your team needs the email and phone number next to each record so they can send messages or make follow-ups. That’s where VLOOKUP comes in:

1. Click in the first blank Email cell in the service log.
2. Type: =VLOOKUP(
3. Click the Customer ID in that row and type a comma.
4. Go to the Customer Directory and select the entire table range, including ID, name, email, and phone number.
5. Type a comma, then put 3 (because email is the third column in this table).
6. Type a comma, then FALSE, so it does an exact match.
7. Close the parentheses.

The full formula looks like this: =VLOOKUP(A2,CustomerDirectory!$A$2:$D$4,3,FALSE), and when you press Enter, Excel finds the matching customer ID in the directory and returns the email for you. Then you repeat the formula for the phone number, changing the column number to 4 before you hit Enter. Once this is done, you drag these formulas down for the rest of the rows so all your service records get the right email and phone attached.

As you can see, VLOOKUP does the job, but it has two practical drawbacks for everyday business use:

• It assumes the Customer ID must be the first column in your directory table.
• It only returns data to the right of that first column.
• If someone adds or moves a column later, you have to update the formula.

It’s useful and good to know, but let’s jump into XLOOKUP to see why it might become your go-to choice for lookups.

XLOOKUP: A More Flexible Customer Lookup

With XLOOKUP, you tell Excel exactly where to find the matching ID and exactly what you want returned. Unlike with the other lookup options, it doesn’t care where the column lives, which makes spreadsheets more stable and easier for your team to maintain. Assuming we are using the same Customer Directory and Service Log from the example above, let’s go through an XLOOKUP example:

1. Click in the blank Email cell next to your first service entry.
2. Type: =XLOOKUP(
3. Click the Customer ID in that row (e.g., A2) and type a comma.
4. Switch to the Customer Directory and select just the Customer ID column and type a comma.
5. Then select the Email column and close the parentheses.

This time, the full formula looks like this: =XLOOKUP(A2,CustomerDirectory!$A$2:$A$4,CustomerDirectory!$C$2:$C$4), and once you press Enter, Excel finds the matching ID and returns the corresponding email.

To pull the phone number, use the same pattern but with the phone column as the return range: =XLOOKUP(A2,CustomerDirectory!$A$2:$A$4,CustomerDirectory!$D$2:$D$4).

That’s all there is to it; your service log shows the correct contact info in every row, and if someone later changes the order or adds a new column to the directory, these formulas don’t break. That’s because XLOOKUP looks for the customer identifier and return field independently, so it doesn’t rely on a fixed column order like VLOOKUP does.

What This Means for Your Team

Think about a morning in your office; someone opens the Service Log to start calls and emails for the day. Before using lookups, that person might flip back and forth between tabs, hunting for the right customer’s email or phone, copying it over, and hoping they didn’t grab the wrong row. It’s a small task, but repeated dozens of times, it’s the kind of repetition that wears people down and invites mistakes.

With lookups in place, the moment someone enters a Customer ID into the service sheet, the contact details appear automatically, with no more hunting, copying, or wondering if the phone number was correct. New hires no longer have to memorize where every column lives or learn the quirks of someone else’s formulas because they type the customer identifier, and Excel fills in the rest. Overall, it frees employees to focus on the work that actually moves the business forward, such as speaking with customers, solving their problems, and building relationships.

And the best part is that when your business grows or your lists change, the lookup setup keeps working. You can add a new column to your customer directory without breaking your formulas, or change the field order, and Excel still finds the right values. That stability becomes a daily upgrade in how work gets done, with less busywork, fewer errors, and more confidence that the tools your team uses are reliable.
