Mastering LEN in Excel – Count Characters in Any Cell

The LEN function counts how many characters (including spaces) are in a cell. It’s perfect for data validation and cleaning tasks.

🔹 Syntax:

=LEN(text)

🔹 Example:

Count characters in cell A2:

=LEN(A2)

🔹 Use Cases:

• 🧹 Find and remove extra-long entries
• 🧾 Check mobile numbers or ID lengths
• 💡 Combine with IF for validation

🔹 Pro Tip:

Use with TRIM to remove extra spaces first:

=LEN(TRIM(A2))

🔚 Wrap-Up:

LEN is a quick way to spot inconsistencies, clean data, or apply length-based rules in Excel.
