Hexadecimal to decimal in excel

Sometimes we use hexadecimal numbers to mark products in daily life, and we want to convert these hexadecimal numbers to decimal numbers in some situations. We can convert number between two number types by convert tool online, actually we can also convert numbers by function in excel as well. In excel, =HEX2DEC(number) can help you to convert hexadecimal number to decimal properly, and on the other side, you can use =DEX2HEX(number) to convert decimal to hexadecimal number.

As we mentioned above, we can use HEX2DEC function to convert numbers conveniently. Just prepare a table with two columns, one column is used for recording HEX numbers, the second column is used for saving the converted decimal numbers.

Step 1: in B1 enter the formula =HEX2DEC(A2).

Step 2: Click Enter to get returned value. So 21163 in B2 is the mapping decimal number for 52AB.

Step 3: Drag the fill handle down to fill the following cells.

Verify that all hexadecimal numbers are converted to decimal numbers correctly. You can also double check the result by convert tool online to make sure the result is correct.

Note:

Sometimes hexadecimal numbers are displayed like 0x52AB, user can remove 0x before 52AB and then use HEX2DEC function to convert number.

Part 2. Convert Decimal to Hex Number in Excel

Prepare another table, the first column is Decimal, the second column is Hex Number.

Step 1: in B10 enter the formula =HEX2DEC(A2).

Step 2: Click Enter to get returned value. So 4D2 in B10 is the mapping hex number for 1234.

Step 3: Drag the fill handle down to fill the following cells.

Note:

There are some other functions to convert numbers between different types. See below screenshot.

Numbers can be classified into four types: decimal, binary, octal, and hexadecimal. The base values of binary numbers, decimal numbers, octal numbers, and hex numbers are 2, 10, 8, and 16 respectively. We can convert a hex number to a decimal number using formulas in Excel.

A hex number has a base value of 16, and the base values are 0–9 and A–F alphabets. A decimal number has a base of 10, and the base values are 0-9. The base values of an octal number are 0-7. In this tutorial, we will show how you can convert hexadecimal numbers to decimal numbers in Excel and vice versa.

How To Convert Hex Number to Decimal Number

Here we will use the formula to get the first result, then use the auto-fill handle to get all the results. Let us look at a simple procedure for converting a hexadecimal number to a decimal number in Excel using formulas.

Step 1:

Consider an Excel sheet with a list of hexadecimal numbers similar to the image below.

Now click on the empty cell in our case, cell B2, and enter the formula as =HEX2DEC(A2) and click Enter to get our first result, as shown in the below image.

Step 2

Now to get all the results, drag down from the first result using the auto-fill handle, and our final result will be similar to the below image.

We can use the formula =DEC2HEX(A2) to convert any decimal number to a hex number. In the formula, A2 is the address of our values.

Note − In the formula, we can use any combination to convert our values. The first name is our existing number, and the second name is the number we are converting.

• BIN – Binary

• HEX – Hexadecimal number

• Oct – Octal number

• DEC – Decimal number

Conclusion

In this tutorial, we used a simple example to demonstrate how you can convert a hexadecimal number to a decimal number in Excel.

HEX2DEC is limited to 10 characters, but that doesn’t mean we can’t use it. Simply use it several times, to convert 10 characters at a time and apply the appropriate power of 2 to each use.

= HEX2DEC(RIGHT(C8,10))+HEX2DEC(MID(C8,3,5))*POWER(16,10)

[Disclaimer: Untested at the moment]

Later: I’m now at a spreadsheet, ready to test. Change the 3,5 in MID to 3,6. Hmm.. Still not right.

Turns out that the HEX2DEC is working on signed hex values, so the first term ends up being negative. Not sure why, but here is the fixed version that adds 2^40 (or 16^10, as we’re working in hex) to fix:

= HEX2DEC(RIGHT(C8,10))+POWER(16,10) + HEX2DEC(MID(C8,3,6))*POWER(16,10)

However, that only works if the RIGHT(C8,10) happens to be negative. Here’s my general solution:

= HEX2DEC(RIGHT(C8,10))+IF(HEX2DEC(RIGHT(C8,10))<0,POWER(16,10),0) + HEX2DEC(MID(C8,3,6))*POWER(16,10)

Ugggh.

In this article, we will learn about how to use the HEX2DEC function in Excel.

HEX2DEC function in excel is used to convert Hexadecimal representation of numbers of radix 16 to Decimal numbers (radix = 10).

The table shown below shows you some of the most used base & their radix of Alpha — numeric characters

Hexadecimal number is representation of a number of radix 16. 10 digits starting from 0, 1, 2, 3, 4, 5, 6, 7, 8 ,9 along with 6 alphabets starting from A, B, C, D, E & F where Decimal number representation have 8 digits from 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The below table will help you understand better.

Conversion formulation is shown below:

4A3

1. Separate the digits
2. Multiply the separated digit with 16⁰, 16¹,16², 16³ and so on starting from the rightmost digit correspondingly.
3. Get the sum of all the multiplied numbers. There it is our decimal number

The HEX2DEC function converts the Hexadecimal number of radix 16 to the Decimal number of radix 10.
Syntax:

=HEX2DEC ( number, [places] )

Number : Hexadecimal number which returns the 10 character Decimal number.
[Places] : [optional] number where result expressed upto the number.
The input value to the function cannot contain more than 10 characters ( 10 bits ). Where first number returns the sign of the number (positive or negative) & Other 9 returns the value after the sign.

To get a negative number, input number must have 10 characters starting with first bit as it represents the negative sign. The negative number is calculated using two’s complement notation. Any less than 10 characters, the function considers default 0s in front.

Now let’s get more understanding of the function via using them in some examples.

Here we have some Hexadecimal values in Hexadecimal Column. We need to convert these Hexadecimal numbers to Decimal value.

Use the formula in Hexadecimal column:

=HEX2DEC (A2)

A2 : number provided to the function as cell reference or text in quotes

Values to the HEX2DEC function is provided as cell reference.

The HEX2DEC representation of 2 of base 16 (hexadecimal) is 2 of base 10 (decimal).

2₁₆= 2₁₀

Now copy the formula to other cells using the Ctrl + D shortcut key.

As you can see here the HEX2DEC function returns the result of the input values.

Notes:

1. Numbers can be given as argument to the function directly with quotes or cell reference in excel.
2. The function doesn’t consider the [places] number in case of a negative decimal number.
3. If the input Hexadecimal number is negative it cannot be less than 1FFFFFFF and if the number is positive it cannot be greater than FFE0000000 .
4. If the input [places] number is not an integer, it is truncated by the function.
5. The function returns the Decimal value for the max value of + 536870911 & minimum value upto — 536870912 (only integers).
6. The function returns the #NUM! Error
   1. If the input Hexadecimal number is less than 1FFFFFFF or greater than FFE0000000 .
   2. If the input number [places] is zero or negative.
   3. If the input number [places] is not sufficient for the resulting positive Decimal number.
7. The function returns the #VALUE! Error
   1. If the input [places] number is text or non-numeric.

I am trying to convert a Hexadecimal value to a decimal one in excel with this reference.

Used parameters and formulas:

Input Hex value : 0x044F3B9AFA6C80 and expected output : 1213017328610432

• Method1: Applying excel formula

‘=HEX2DEC(RIGHT(D3164,10))+HEX2DEC(MID(D3164,3,4))*POWER(16,10)‘

Actual output : 1213017328610430

• Method2: Using VBA macro:

    ' Force explicit declaration of variables
    Option Explicit

    ' Convert hex to decimal
    ' In:   Hex in string format
    ' Out:  Double

    Public Function HexadecimalToDecimal(HexValue As String) As Double

    ' If hex starts with 0x, replace it with &H to represent Hex that VBA will understand
    Dim ModifiedHexValue As String
    ModifiedHexValue = Replace(HexValue, "0x", "&H")

    HexadecimalToDecimal = CDec(ModifiedHexValue)
    End Function

Actual output : 1213017328610430

When I try to convert this value with online conversion tool or with python script, it covert expected decimal value.

Please any hint on issue will be more helpful.
