How to use HSTACK function in Excel?

The `HSTACK` function in Excel is used to horizontally stack arrays or ranges. It combines multiple ranges or arrays into a single array, placing them side by side. This function is particularly useful for combining data without having to copy and paste manually. Here’s how you can use the `HSTACK` function:

Syntax

=HSTACK(array1, [array2], ...)
  • array1: The first array or range that you want to stack horizontally.
  • array2, …: Additional arrays or ranges that you want to stack next to the first one. You can add as many additional arrays as needed.

Example

Suppose you have the following data:

  Apple
  Banana
  Cherry
  X
  Y
  Z
  • Array A in cells A1:A3:
  • Array B in cells B1:B3:

To combine these arrays horizontally, you would use the `HSTACK` function like this:

   =HSTACK(A1:A3, B1:B3)
  • Select the cell where you want the combined array to start, for example, cell C1.
  • Enter the formula:
  • Press Enter.

The result in cells C1:D3 would be:

Apple  X
Banana Y
Cherry Z

Key Points

  • The `HSTACK` function is available in Microsoft 365 and Excel 2021, so ensure your version supports this function.
  • All arrays must have the same number of rows. If they don’t, the function will return a `#VALUE!` error.
  • The function is ideal when working with dynamic arrays, as it automatically adjusts the output when the source data changes.

Use Cases

  • Data Consolidation: Quickly combine data from different columns for summary reports or dashboards.
  • Dynamic Reports: Use with other dynamic array functions for advanced data manipulation and analyses.
  • Data Visualization Preparation: Prepare data in the format needed for charts and other visualization tools.

By using `HSTACK`, you can streamline your data management and create flexible, dynamic Excel reports.
