Automating JPG Image Downloads in Excel with VBA

 

💡 Introduction

Have you ever needed to check if a cell contains special characters like @, #, $, %, & in Excel? Instead of manually scanning your data, you can use a powerful Excel formula to detect these characters automatically! 🚀

📝 Formula to Detect Special Characters

=SUMPRODUCT(--ISNUMBER(SEARCH({"!","@","#","$","%","^","&","~*","(",")","_","+","=","{","}","[","]","|","\",":",";","'","""","<",">",",",".","~?","/","~~","`"}, A1)))>0

🔍 How This Formula Works

✅ SEARCH Function:

• Checks if any special character from the given list {...} exists in cell A1.
• If a match is found, it returns the position of the character; otherwise, it returns an error.

✅ ISNUMBER Function:

• Converts the SEARCH results into TRUE (if a number is found) or FALSE (if an error occurs).

✅ Double Unary (--) Operator:

• Converts TRUE/FALSE values into 1 and 0.

✅ SUMPRODUCT Function:

• Sums up the 1s (matches found) and 0s (no matches).

✅ Comparison >0:

• If the sum is greater than 0, the formula returns TRUE (meaning a special character exists).
• Otherwise, it returns FALSE (meaning no special character is present).

🎯 Example Use Case

A (Input Text)	Formula Output
Hello123	FALSE (No special characters)
Hello@World	TRUE (Contains @)
Excel_Formula!	TRUE (Contains _ and !)
Test	FALSE (No special characters)
