Function ที่ใช้ในการแปลง ตัวเลขเป็นตัวเขียนภาษาอังกฤษ

 

สำหรับท่านที่เคยใช้ Function "BAHTTEXT" ใน Excel ที่ใช้ในการแปลง ตัวเลขเป็นอักษรภาษาไทย คงจะคุ้นเคยดีอยู่แล้ว แต่ถ้าเราต้องการจะแปลงเป็นภาษาอังกฤษหละ ใน Excel กลับไม่มี Function เหมือน "BAHTTEXT" ให้ ดังนั้นเราจึงต้องสร้างเอง ดังตัวอย่างข้างล่างนี้ หรือถ้าต้องการจะดาวน์โหลดไฟล์ Excel ก็ให้ คลิกที่นี่

' If we find decimal place...
