Convert Number to Text in Excel: A Complete Guide

When preparing vouchers, sales invoices, or financial reports in Excel, it’s often necessary to spell out numeric amounts in words. For example, converting 123.50 to “One Hundred Twenty-Three Taka and Fifty Paise Only”. Unfortunately, Excel doesn’t have a built-in feature to do this—but with a little VBA, you can make it happen!

In this blog, we’ll walk you through how to create a custom Excel function called SpellNumber using VBA to convert numbers to text in a format commonly used in Bangladesh, India, and other countries where “Taka” and “Paise” are used.

🔧 Why Convert Numbers to Words?

Spelled-out amounts are often used in:

• Bank cheques
• Sales invoices
• Payment vouchers
• Formal contracts
• Accounting records

They help avoid tampering and reduce ambiguity in financial documents.

✅ Step-by-Step: Add the SpellNumber Function in Excel

Step 1: Open the VBA Editor

• Open your Excel workbook.
• Press ALT + F11 to launch the Visual Basic for Applications (VBA) editor.

Step 2: Insert a Module

• In the editor, click Insert → Module.
• A blank code window will appear.

Step 3: Paste the SpellNumber Code

Copy and paste the following code into the module:

Function SpellNumber(amt As Variant) As String
Application.Volatile

Dim FIGURE As String
Dim FIGLEN As Integer
Dim i As Integer
Dim WORDs(19) As String
Dim tens(9) As String

' Initialize number words
WORDs(1) = "One"
WORDs(2) = "Two"
WORDs(3) = "Three"
WORDs(4) = "Four"
WORDs(5) = "Five"
WORDs(6) = "Six"
WORDs(7) = "Seven"
WORDs(8) = "Eight"
WORDs(9) = "Nine"
WORDs(10) = "Ten"
WORDs(11) = "Eleven"
WORDs(12) = "Twelve"
WORDs(13) = "Thirteen"
WORDs(14) = "Fourteen"
WORDs(15) = "Fifteen"
WORDs(16) = "Sixteen"
WORDs(17) = "Seventeen"
WORDs(18) = "Eighteen"
WORDs(19) = "Nineteen"

tens(2) = "Twenty"
tens(3) = "Thirty"
tens(4) = "Forty"
tens(5) = "Fifty"
tens(6) = "Sixty"
tens(7) = "Seventy"
tens(8) = "Eighty"
tens(9) = "Ninety"

' Convert the amount to a string with 2 decimal places
FIGURE = Format(amt, "0.00")
FIGLEN = Len(FIGURE)

' Pad to ensure consistent processing
If FIGLEN < 12 Then
    FIGURE = Space(12 - FIGLEN) & FIGURE
End If

SpellNumber = ""

' Process Crore, Lakh, Thousand
For i = 1 To 3
    If Val(Left(FIGURE, 2)) < 20 And Val(Left(FIGURE, 2)) > 0 Then
        SpellNumber = SpellNumber & WORDs(Val(Left(FIGURE, 2)))
    ElseIf Val(Left(FIGURE, 2)) >= 20 Then
        SpellNumber = SpellNumber & tens(Val(Left(FIGURE, 1)))
        If Val(Right(Left(FIGURE, 2), 1)) > 0 Then
            SpellNumber = SpellNumber & " " & WORDs(Val(Right(Left(FIGURE, 2), 1)))
        End If
    End If

    If i = 1 And Val(Left(FIGURE, 2)) > 0 Then
        SpellNumber = SpellNumber & " Crore "
    ElseIf i = 2 And Val(Left(FIGURE, 2)) > 0 Then
        SpellNumber = SpellNumber & " Lakh "
    ElseIf i = 3 And Val(Left(FIGURE, 2)) > 0 Then
        SpellNumber = SpellNumber & " Thousand "
    End If

    FIGURE = Mid(FIGURE, 3)
Next i

' Process Hundreds
If Val(Left(FIGURE, 1)) > 0 Then
    SpellNumber = SpellNumber & WORDs(Val(Left(FIGURE, 1))) & " Hundred "
End If

FIGURE = Mid(FIGURE, 2)

' Process Tens and Units
If Val(Left(FIGURE, 2)) < 20 And Val(Left(FIGURE, 2)) > 0 Then
    SpellNumber = SpellNumber & WORDs(Val(Left(FIGURE, 2)))
ElseIf Val(Left(FIGURE, 2)) >= 20 Then
    SpellNumber = SpellNumber & tens(Val(Left(FIGURE, 1)))
    If Val(Right(Left(FIGURE, 2), 1)) > 0 Then
        SpellNumber = SpellNumber & " " & WORDs(Val(Right(Left(FIGURE, 2), 1)))
    End If
End If

' Move to decimal (Paise)
FIGURE = Mid(FIGURE, 4)

If Val(FIGURE) > 0 Then
    SpellNumber = SpellNumber & " Paise "
    If Val(Left(FIGURE, 2)) < 20 Then
        SpellNumber = SpellNumber & WORDs(Val(Left(FIGURE, 2)))
    Else
        SpellNumber = SpellNumber & tens(Val(Left(FIGURE, 1)))
        If Val(Right(Left(FIGURE, 2), 1)) > 0 Then
            SpellNumber = SpellNumber & " " & WORDs(Val(Right(Left(FIGURE, 2), 1)))
        End If
    End If
End If

' Add "Taka Only"
If Val(amt) > 0 Then
    SpellNumber = SpellNumber & " Taka Only"
End If
End Function

Step 4: Save and Close the VBA Editor

Press Ctrl + S to save. Then close the VBA editor.
⚠️ If prompted, save the file as a macro-enabled workbook (.xlsm).
