10 Excel Lookup Tricks For Combining Two Columns

Excel is a powerful tool that can transform data handling from a cumbersome task to an efficient process. When you're dealing with datasets, one common challenge many face is the need to combine two columns effectively. Fortunately, Excel provides a variety of lookup tricks that can help you do just that. In this blog post, we'll explore 10 essential Excel lookup tricks for combining two columns, each designed to enhance your productivity and streamline your data analysis. Let’s dive in!

Understanding Excel Lookup Functions

Before we jump into the tricks, it's important to familiarize ourselves with some key lookup functions:

• VLOOKUP: This function searches for a value in the first column of a range and returns a value in the same row from another column.
• HLOOKUP: Similar to VLOOKUP, but searches for a value in the first row and returns a value in the same column from a specified row.
• INDEX: This function returns the value of a cell in a specific row and column within a given range.
• MATCH: This function returns the relative position of a specified value within a range.

Trick 1: VLOOKUP with Concatenated Values

One handy way to combine two columns is to create a new column that concatenates the values from the two columns, and then use VLOOKUP to fetch related information.

1. Create a new column where you concatenate the values.

   • Formula: =A2 & B2

2. Use VLOOKUP to find data based on the concatenated value.

   • Formula: =VLOOKUP(D2, E:F, 2, FALSE)

Trick 2: HLOOKUP for Horizontal Data

If your data is laid out horizontally, HLOOKUP comes to the rescue. Follow similar steps as above, but ensure you adjust your ranges to fit the horizontal layout.

1. Concatenate your values horizontally.

   • Formula: =A1 & B1

2. Then, utilize HLOOKUP to search for these concatenated values.

Trick 3: Combining Values with TEXTJOIN

For Excel versions that support TEXTJOIN (Excel 2016 and later), this function can simplify combining values from two columns.

1. Use TEXTJOIN in a new column:

   • Formula: =TEXTJOIN("-", TRUE, A2, B2)

2. You can then use this result with lookup functions as needed.

Trick 4: Index-Match for Greater Flexibility

For more advanced users, combining INDEX and MATCH allows for more flexibility than VLOOKUP.

1. Concatenate your columns like before.

   • Formula: =A2 & B2

2. Use the combination with INDEX and MATCH:

   • Formula: =INDEX(C:C, MATCH(D2, A:A&B:B, 0))

Trick 5: Use of Filter Function for Unique Combinations

Another useful Excel function is FILTER, available in newer versions. You can create a new dynamic array of unique combinations:

1. Use FILTER to get unique combinations of values:
   • Formula: =FILTER(A2:B10, A2:A10<>"")

Trick 6: Creating a Pivot Table for Combining Data

If you want a summary or aggregated view from your two columns, a Pivot Table can serve well.

1. Highlight your data, go to Insert -> Pivot Table.
2. Drag your columns into Rows and Values to create a combination summary.

Trick 7: Utilizing CONCATENATE for Classic Users

For those using older versions of Excel, CONCATENATE still does the job.

1. Create a new column for concatenation:

   • Formula: =CONCATENATE(A2, " ", B2)

2. You can then reference this in your lookups.

Trick 8: Flash Fill for Quick Combining

Flash Fill is a great tool if you’re working with patterns. Just start typing the combined values next to your two columns, and Excel might offer suggestions.

1. Type the desired output next to the two columns, then press Ctrl + E.

Trick 9: IFERROR to Handle Lookup Errors

Whenever you perform lookups, you might encounter errors. Wrapping your VLOOKUP or other functions in IFERROR can provide a smoother experience.

1. Formula Example:
   • =IFERROR(VLOOKUP(D2, E:F, 2, FALSE), "Not Found")

Trick 10: Data Validation for Consistency

To ensure that the data you are working with in your two columns remains consistent, utilize Data Validation.

1. Highlight your columns, go to Data -> Data Validation.
2. Choose settings that restrict values to a list or specific criteria to avoid errors.

<table> <tr> <th>Trick Number</th> <th>Trick Description</th> </tr> <tr> <td>1</td> <td>VLOOKUP with Concatenated Values</td> </tr> <tr> <td>2</td> <td>HLOOKUP for Horizontal Data</td> </tr> <tr> <td>3</td> <td>Combining Values with TEXTJOIN</td> </tr> <tr> <td>4</td> <td>Index-Match for Greater Flexibility</td> </tr> <tr> <td>5</td> <td>Use of Filter Function for Unique Combinations</td> </tr> <tr> <td>6</td> <td>Creating a Pivot Table for Combining Data</td> </tr> <tr> <td>7</td> <td>Utilizing CONCATENATE for Classic Users</td> </tr> <tr> <td>8</td> <td>Flash Fill for Quick Combining</td> </tr> <tr> <td>9</td> <td>IFERROR to Handle Lookup Errors</td> </tr> <tr> <td>10</td> <td>Data Validation for Consistency</td> </tr> </table>
