Скачать или смотреть Excel LEN Function - Count Characters in Text

In this short, you'll learn:
✅ LEN function
✅ Counts ALL characters (letters, numbers, spaces, punctuation)
✅ Essential for data validation and text analysis

What LEN counts:
Every single character including:
Letters (A-Z, a-z)
Numbers (0-9)
Spaces (each space = 1 character)
Punctuation (!, ?, ., etc.)
Special characters (@, #, $, etc.)

Examples:
"Excel" → =LEN(A2) → 5
"John Doe" → =LEN(A3) → 8 (space counts!)
"Hello World!" → =LEN(A4) → 12 (space + punctuation)

⚠️ Important: Spaces count as characters!
"John Doe" = 8 characters (not 7!)

Practical uses:
✅ Data validation (password length checks)
✅ Character limits (Twitter, SMS)
✅ Find data issues (cells with only spaces)
✅ Combining with other functions (RIGHT, LEFT, MID)

Common applications:
Check password length
Character limit check
Find empty-looking cells

💡 Pro Tip: Combine with TRIM: =LEN(TRIM(A2)) to count without extra spaces!

Essential building block for text formulas!
