Capture Last Entered Value in Excel

Objective

To create an Excel formula that captures the last entered value from a specified range of cells.

Formula Solution

To achieve this, you can use the following formula:

=LOOKUP(2,1/(A:A<>""),A:A)

Formula Explanation

• LOOKUP Function: This is the primary function used to retrieve the last entered value.
• 2: This value is larger than any expected number of entries, ensuring the function scans through the entire array until it finds the last non-empty entry.
• 1/(A:A<>""): This part creates an array where each non-empty cell in column A returns a value of 1 and empty cells return a divide by zero error. The LOOKUP function ignores errors, allowing it to focus solely on the cells with values.
• A:A: This indicates the range from which to look up the last value. Adjust this range as necessary for your specific worksheet.

Practical Example

Assume you have data in column A, and you want another cell (let's say B1) to always reflect the last entry from column A.

1. In cell B1, enter the formula:

   =LOOKUP(2,1/(A:A<>""),A:A)

2. As you enter or modify data in column A, cell B1 will instantly display the last value entered, whether it's text, a number, or a date.

Implementation Note

• Make sure that the specified range (A:A in this case) is correctly set to your actual data range. For performance reasons, restricting the range to a specific segment (e.g., A1:A100) instead of the entire column may be beneficial for large datasets.

Conclusion

The provided formula is efficient for capturing the last entered value in a specified range of cells. It is versatile enough to work with various data types and can be modified for different ranges as needed.

By harnessing this method, users can significantly enhance their data management capabilities in Excel, especially for tracking the most recent entries in a dynamic dataset. To further deepen your Excel skills, consider exploring the offerings on the Enterprise DNA Platform.
