How to Use the BIN2OCT Function in Google Sheets


Google Sheets is a powerful tool that helps us manage and manipulate data effectively. One of its useful functions is BIN2OCT, which allows us to convert binary numbers to their octal (base-8) equivalents. This can be particularly handy when working with computer science or any field where binary numbers are involved. In this article, we will walk you through the basics of using the BIN2OCT function in Google Sheets.

When to Use BIN2OCT Function

The BIN2OCT function comes into play when you have binary numbers that need to be converted to octal format. Binary numbers, which are composed of only 0s and 1s, are used extensively in computer science. Octal numbers, on the other hand, are base-8 numbers that use digits from 0 to 7. The conversion is necessary when you’re dealing with computer systems and networks, as they often use octal representation.

How to use BIN2OCT function in Google Sheets

  1. Type “=BIN2OCT” or go to the “Insert” tab ➝ “Function” ➝ “Engineering ” ➝ “BIN2OCT”.

BIN2OCT(signed_binary_number, [significant_digits])

  • signed_binary_number – The signed 10-bit binary value to be converted to signed octal, provided as a string.
    • The most significant bit of signed_binary_number is the sign bit; that is, negative numbers are represented in two’s complement format.
    • For this function, this value has a maximum of 0111111111 if positive, and a minimum of 1000000000 if negative.
    • If signed_binary_number is provided as a valid binary number, it will automatically be converted to the appropriate string input. For example, BIN2OCT(11111) and BIN2OCT("11111") yield the same result: 37.
  • significant_digits – [ OPTIONAL ] – The number of significant digits to ensure in the result.
    • If this is greater than the number of significant digits in the result, the result is left-padded with zeros until the total number of digits reaches significant_digits. For example, BIN2OCT("11111") yields the value 00000037.
    • This value is ignored if the most significant bit of signed_binary_number is 1; that is, if the expressed signed_binary_number is greater than or equal to 1000000000.

Tips for Optimization

Optimizing the BIN2OCT function in Google Sheets can help improve the efficiency and performance of your spreadsheet. Here are some tips to consider:

  1. Minimize the Number of Function Calls:
    • Instead of applying the function to each individual cell, consider using array formulas to process multiple cells at once. This reduces the number of function calls, which can significantly improve performance.
  2. Avoid Using Volatile Functions:
    • Volatile functions like NOW(), TODAY(), and RAND() recalculate every time any change occurs in the spreadsheet. Minimize their usage, especially within the BIN2OCT formula, as they can slow down your sheet.
  3. Use Helper Columns:
    • If possible, use additional columns to perform intermediate calculations before using the BIN2OCT function. This can simplify the main formula and potentially improve performance.
  4. Limit the Range of Data:
    • Apply the function only to the range of data that requires conversion. Avoid unnecessarily large ranges, as they can slow down your spreadsheet.
  5. Avoid Nested Functions:
    • Minimize the use of nested functions within BIN2OCT. Complex nesting can increase computation time. Instead, break down the problem into simpler steps if possible.
  6. Optimize the Data Structure:
    • Ensure that your data is structured efficiently. For example, if you have a range of binary numbers, make sure they’re stored in a way that allows for easy processing.
  7. Avoid Excessive Conditional Formatting:
    • Too much conditional formatting can slow down Google Sheets. Use it judiciously and consider simplifying rules where possible.
  8. Turn Off Automatic Calculation:
    • If your spreadsheet contains a large dataset and multiple complex formulas, consider turning off automatic calculation (Formulas > Calculation > Manual) and manually trigger calculations when needed.
  9. Clear Unused Data:
    • If you have large datasets with unused rows or columns, consider removing them to reduce the computational load.
  10. Use Scripting (Google Apps Script):
    • For very complex operations, consider using Google Apps Script to create a custom function tailored to your specific needs.
  11. Avoid Circular References:
    • Circular references can slow down your spreadsheet significantly. Resolve any circular references in your formulas.
  12. Check for External References:
    • If your spreadsheet contains external references to other sheets or workbooks, ensure that those references are up-to-date.

Real-World Application

The BIN2OCT function in Google Sheets is used to convert a binary number to its octal (base-8) representation. This can be particularly useful in various scenarios where you’re working with binary data and need to represent it in a different base. Here are some real-world applications of the BIN2OCT function:

  1. Digital Electronics and Computer Science:
    • In computer science and digital electronics, data is often represented in binary form. However, in some cases, it’s more convenient to work with numbers in octal. The BIN2OCT function can help in converting binary data to octal.


    • You might be working with binary-coded decimal (BCD) numbers in a digital circuit. Converting these to octal can make certain calculations or comparisons more straightforward.
  2. File Permissions in Unix-Like Systems:
    • In Unix and Unix-like operating systems, file permissions are often represented in octal notation. If you’re dealing with binary representations of file permissions (like 110101010 for read, write, execute permissions), you can use BIN2OCT to convert them to octal.


    • You want to change the permissions of a file using the chmod command in a Unix terminal. You have the permissions in binary format and want to convert them to octal.
  3. Network Administration:
    • Subnet masks, which are used in computer networking, are sometimes represented in binary. Converting these to octal can help in certain network configurations.


    • You’re setting up a network and need to configure a subnet mask. You have it in binary format and need to convert it to octal.
  4. Educational Purposes:
    • The BIN2OCT function can be used in educational settings to teach binary, octal, and other numeral systems. It helps students understand the relationship between different bases.


    • A teacher might use it in a lesson on numeral systems to demonstrate the conversion process.
  5. Data Analysis and Reporting:
    • In some cases, data analysts might work with binary data that needs to be converted to octal for reporting or further analysis.


    • You’re analyzing data from a source that provides certain information in binary format. To include this data in a report, you need to convert it to octal.
  6. Security and Encryption:
    • In some cryptographic algorithms, operations might be performed on binary representations of keys or data. Converting these representations to octal can be useful in certain cryptographic processes.


    • You’re working on a cryptographic algorithm and need to perform operations on keys represented in binary. Converting them to octal could be a step in the process.


In conclusion, the BIN2OCT function in Google Sheets proves to be a valuable tool for converting binary numbers to their octal counterparts. Its straightforward syntax and ease of use make it a go-to function for anyone working with numeral systems in spreadsheets. By incorporating best practices like using cell references, minimizing function calls, and combining functions judiciously, you can optimize the usage of BIN2OCT and enhance the efficiency of your spreadsheet calculations.

Remember to validate data inputs, keep formulas readable, and test results for accuracy. These steps will not only streamline your workflow but also ensure the integrity of your calculations.
