The HEX2BIN function is an Engineering function that converts a signed hexadecimal number to a signed binary number. It returns a text string and is commonly used in computer science and engineering fields.


Use the HEX2BIN formula with the syntax shown below, it has 1 required parameter and 1 optional parameter:

=HEX2BIN(signed_hexadecimal_number, [significant_digits])
  1. signed_hexadecimal_number (required):
    The signed hexadecimal number to be converted.
  2. significant_digits (optional):
    An optional parameter specifying the number of significant digits to return in the binary number. If omitted, the function will return the full binary number.


Here are a few example use cases that explain how to use the HEX2BIN formula in Google Sheets.

Converting hexadecimal numbers to binary

The HEX2BIN function can be used to quickly convert hexadecimal numbers to binary numbers in engineering and computer science fields.

Working with signed binary numbers

The HEX2BIN function can be used to convert signed hexadecimal numbers to signed binary numbers, which is useful in many engineering applications.

Common Mistakes

HEX2BIN not working? Here are some common mistakes people make when using the HEX2BIN Google Sheets Formula:

Incorrect input format

The signed_hexadecimal_number argument should be a signed hexadecimal number, with a maximum of 10 characters (40 bits). If the input is not in the correct format, the formula will return an error.

Missing argument

The HEX2BIN formula requires at least one argument, the signed_hexadecimal_number. If the significant_digits argument is not provided, the formula will use the default value of 10 significant digits.

Invalid significant_digits argument

The significant_digits argument should be a positive integer between 1 and 10. If the argument is not a valid integer or is outside of this range, the formula will return an error.

Incorrect output format

The HEX2BIN formula returns a binary number as a text string. If the cell format is not set to text, the formula result may be displayed as a number in scientific notation or as a date.

Unsupported input

The HEX2BIN formula only supports signed hexadecimal numbers. If the input is not a signed hexadecimal number, the formula will return an error.

The following functions are similar to HEX2BIN or are often used with it in a formula:


    The BIN2HEX function converts a signed binary number to hexadecimal format. This function is commonly used in engineering and scientific fields where binary numbers are used to represent data. The output of this function is a text string in hexadecimal format.


    The HEX2DEC function converts a signed hexadecimal number to its decimal equivalent. This function is commonly used in engineering calculations where hexadecimal numbers are used to represent signed values.


    The DEC2HEX formula is an engineering formula in Google Sheets that converts a decimal number to its hexadecimal equivalent. It is commonly used to convert numbers to a format that is easier to read and work with in certain applications.
