Exploring Additional Useful Functions in Excel: NUMBERVALUE, UNICHAR, UNICODE, and FORMULATEXT

Excel is known for its wide range of built-in functions that help users perform everything from basic calculations to advanced data analysis. While many users are familiar with the core functions, Excel also offers a variety of additional functions that can streamline workflows and improve efficiency. Four such functions—NUMBERVALUE, UNICHAR, UNICODE, and FORMULATEXT—provide unique capabilities that can enhance your Excel experience in powerful ways. Let’s take a closer look at each of these functions and how they can be used.

1. NUMBERVALUE: Converting Text to Numbers Without Locale Issues

The NUMBERVALUE function is designed to convert text strings that represent numbers into actual numeric values. One of the main advantages of NUMBERVALUE is that it operates independently of the locale settings, meaning it can correctly interpret numbers in text form regardless of whether you use commas or periods as the decimal separator.

This is especially useful when dealing with data from different regions, where the decimal separator might differ. For example, in some countries, a period (.) is used as a decimal separator, while in others, a comma (,) is used. NUMBERVALUE eliminates this issue, allowing you to convert text values into numbers seamlessly.

Syntax:

NUMBERVALUE(text, [decimal_separator], [group_separator])

Where:

  • text: The text string representing the number you want to convert.
  • decimal_separator: (Optional) The character used to separate the decimal part of the number (default is the system's locale setting).
  • group_separator: (Optional) The character used to separate groups of thousands (default is the system's locale setting).

Example: If you have the text value "1,234.56" but need to convert it into a number in a system that uses a comma as the decimal separator, you can use:

=NUMBERVALUE("1,234.56", ".", ",")

This will correctly convert the text to the number 1234.56 even in regions where the comma is used as the decimal separator.

2. UNICHAR: Returning Unicode Characters from Numeric Values

The UNICHAR function allows you to return a Unicode character based on a specific numeric value. Every character (including letters, symbols, and emojis) has a unique Unicode code point. With UNICHAR, you can convert a given numeric code point into its corresponding character.

This function is handy when you want to display special characters or emojis in your spreadsheet that may not be easily accessible through your keyboard. It can be useful for creating custom symbols, adding icons to cells, or even displaying characters in data processing workflows.

Syntax:

UNICHAR(number)

Where:

  • number: The Unicode code point (a number) representing the character you want to retrieve.

Example: To return the heart emoji (❤️), you can use the Unicode code point 10084:

=UNICHAR(10084)

This will display the heart symbol (❤️) in the cell.

3. UNICODE: Finding the Unicode Code Point of a Character

The UNICODE function is the reverse of UNICHAR. It returns the Unicode code point of the first character in a text string. This can be useful when you need to identify the numeric value associated with a character or when working with text data that includes special characters or non-standard symbols.

By knowing the Unicode code point of a character, you can better handle text data across different languages, especially when working with international characters or non-Latin alphabets.

Syntax:

UNICODE(text)

Where:

  • text: The text string containing the character whose Unicode code point you want to retrieve.

Example: If you want to find the Unicode code point for the character A, you would use:

=UNICODE("A")

This will return 65, which is the Unicode code point for the letter A.

4. FORMULATEXT: Retrieving the Formula Behind a Cell

The FORMULATEXT function is used to display the actual formula behind a given cell reference as text. This is particularly useful when you want to check, debug, or document formulas in your spreadsheet. Instead of manually copying and pasting the formula from the formula bar, you can use FORMULATEXT to display the formula directly within a cell.

This function is especially helpful for tracking complex formulas, ensuring consistency across your workbook, or reviewing formulas without having to navigate to the formula bar.

Syntax:

FORMULATEXT(reference)

Where:

  • reference: The cell reference containing the formula you want to display as text.

Example: If cell A1 contains the formula =SUM(B1:B5), you can use the FORMULATEXT function to display the formula itself in another cell, like this:

=FORMULATEXT(A1)

This will return the text =SUM(B1:B5), showing the actual formula used in cell A1.

Practical Applications of These Functions

The NUMBERVALUE, UNICHAR, UNICODE, and FORMULATEXT functions are versatile tools that can simplify tasks and improve efficiency. Here are some ways you can apply these functions in your daily work:

  1. Handling Regional Data: If you frequently work with data from different countries or regions, NUMBERVALUE can help you convert numbers represented in different formats without worrying about locale settings. This ensures your data is consistent and easy to analyze.

  2. Incorporating Special Characters: With UNICHAR, you can easily insert special symbols, icons, or emojis into your spreadsheet, enhancing the visual appeal of your reports or making it easier to represent specific information.

  3. Analyzing Text Data: UNICODE is helpful when you need to analyze or process text data, particularly for international or non-standard characters. Knowing the Unicode code point of a character allows you to handle text in a standardized way across languages.

  4. Formula Documentation and Debugging: FORMULATEXT can be used to document your formulas, making it easier for others to understand your calculations or for you to troubleshoot any issues in your spreadsheets.

Conclusion

These additional functions—NUMBERVALUE, UNICHAR, UNICODE, and FORMULATEXT—offer powerful tools for handling data in Excel. Whether you're dealing with international data, special characters, or need a quick way to reference formulas, these functions provide solutions that enhance your workflow and improve efficiency. By mastering these functions, you can take full advantage of Excel’s capabilities and create more dynamic, flexible, and error-free spreadsheets.
