📘 What Is VLOOKUP?

VLOOKUP is a function used to search data vertically based on a specific keyword. It is one of the most widely used Excel functions in workplaces because it can handle product searches, student databases, inventory systems, and automatic dictionary projects like this one.

🧠 Main Formula Used

In this exercise, we use the following combination of functions:

• VLOOKUP → searches for words in the dictionary table
• IFERROR → displays a message if the word is not found
• FALSE → ensures the search result matches exactly

🧭 Steps to Create the Dictionary Data

1. Create a new sheet named Dictionary Data.
2. In column A, enter Indonesian words.
3. In column B, enter the English translations.
4. Return to the main worksheet.
5. Create a search input box.
6. Insert the VLOOKUP formula into the result cell.

🧪 Case Study: Automatic Translation

For example, when the user types:

• Pintu → Door
• Guru → Teacher
• Buku → Book
• Jendela → Window

If the word is not available in the dictionary database, Excel will automatically display: "Not Found".

⚠️ Common Mistakes When Using VLOOKUP

• The table range is not locked
• Incorrect sheet name
• The lookup column is not on the far left
• Forgetting to use FALSE
• Incorrect table or range references
