Brief introduction to lines
A string is a sequence or group of characters of arbitrary length that may or may not have semantic meaning in a language. It can consist of various characters, for example B. Numbers, upper case, lower case, punctuation and symbols.
Examples of strings :
1. Testme123
2. Daniel Dozen
3. Please enter your name.
4. Christmas is on the 25th. December of each year.
5. @$#%$%^
6. 234325fdgdgfd
Formatting of line
From the above examples, we can conclude that each character in a string can be a unique data type, such as a lowercase letter, a number, an uppercase letter, a symbol, or a punctuation mark. In your g-program, there may be situations where a channel needs to be a certain size.
For example:
- The text field can expect the date to be entered in the exact format mm-dd-yyyy.
- Entered numbers can be displayed with the currency symbol.
- The interest rate symbol can be used in conjunction with numbers to indicate values such as the interest rate.
- You can use decimals with numbers to make reading easier.
This formatting can be done using Visual Basic’s application formatting features.
Formatting function
This function provided by the VBA library can be classified as a string or date function. It converts the specified expression to the expected format and returns it as a string.
Syntax
Format ( <string expression> , [ Format ] )
Where
< string expression > is a string to format and
The [ format ] is the format to be applied to the specified string expression. This is an optional parameter, so it is enclosed in square brackets.
The format setting can be a user-defined format or a named format predefined by Excel. Here are some of the listed formats provided by MS Excel.
| Format | Explanation |
| General Information | This is the default number format that applies in MS Excel when we enter only one number. In most cases, numbers formatted in the general format are displayed as we print them. However, if the width of the cell is insufficient to display the whole number, numbers are rounded with decimals in the usual format. This number format also uses scientific notation (exponential form) for high or large numbers that have 12 or more digits. |
| Currency | Used for monetary values and displays the currency symbol with numbers. The default currency symbol is $. You can specify the number of decimal places to be used. For example, we want to use the thousand-digit separator. We can also specify if we want to display a negative number based on its value. |
| Corrected by | This format shall have at least one digit to the left of the decimal point and two digits to the right of the decimal point. |
| Standard | This format displays thousands of separators, at least one digit to the left of the decimal point and two digits to the right of the decimal point. |
| Percentage | This format displays the percentage value – (i.e.) a number divided by 100 with the % sign. Two digits are displayed to the right of the decimal point. |
| Localization Science | Displays the scientific notation. It is a number in exponential notation that replaces part of a number with E+n, where E is the exponent, by multiplying the previous number by the nth power of 10. For example, the scientific number 12345678901 appears in two-digit format as 1.23E+10, or 1.23 times 10 to the power of 10. We can specify the number of decimal places we want to use. |
| Yes/No | This format indicates No if the number is 0 and Yes if the number is not 0. |
| True/False | This format shows False if the number is 0 and True if the number is not 0. |
| on/off | This format indicates Off when the number is 0 and On when the number is not 0. |
| General date | This format displays date and time series numbers as date values, depending on the type and location we specify. Date formats beginning with an asterisk (*) respond to changes in regional date and time settings already set in the Control Panel. Formats not marked with an asterisk are independent of the control panel settings. |
| Long time. | This format displays the date value according to the long date parameters in our system. |
| Average date | This format displays the date value according to the average date set in our system. |
| Short dates | This format displays the date value according to the short date setting in our system. |
| Time | This format displays date and time series numbers as time values, depending on the type and location we specify. Time formats beginning with an asterisk (*) respond to changes in regional date and time settings already set in the Control Panel. Formats not marked with an asterisk are independent of the control panel settings. |
| For a long time. | This format displays the date value according to the long-term configuration of our system. |
| Average duration | This format displays the date value according to the time media setting of our system. |
| Short term | This format displays the value of the date according to the short duration of our system. |
| Number | It is usually used to represent numbers. We can specify the number of decimal places we want to use. For example, we can use the thousand-digit separator. We can also specify if we want to display a negative number based on its value. |
| Accounting | It is also used for monetary values. Align the decimal points of numbers and currency symbols in the column. |
| Group | It displays the number as a fraction according to the type of fraction we specify. |
Examples of using the formatting function
Use a custom format for formattingissues
Sub-format_demo()
Declare variable
Dim str_num
Use the format function and set the value
in str_num = Format(510.3, #,###0.00)
Print the value – it should be 510.30
Debug.Print str_num
Last Subsection
Pre-defined formatting used fornumbers
This example covers the formatting of numbers with percentages, currencies, and decimals.
In_demo_predef() format
Declare variables
Dim str_std, str_per, str_cur, str_shdt
str_std = Format(611.6, Standard)
str_per = Format(0.982, Percent)
str_cur = Format(1369.5, Currency) ‘Assigning values with the format function
Print results
Debug.Print str_std ‘ The result should be : 611.60’
Debugging.Print str_per ‘ The result should be : 98.20%
Debug.Print str_cur ‘ The result should be: ‘1369.50’ if the currency symbol is already defined.

Sample program for displaying date formats
This program displays the data in short and long format. There are some predefined formats that may be of interest to the user.
Sub format_demo_predef()
‘ Declare variables
Dim str_shdt, str_lgdt
Assigning values with the format function
str_shdt = Format(9.9.2013, short date)
str_lgdt = Format(9.9.2013, long date)
Print resultsDebug.Print str_shdt ‘ The result should be: ’09-09-2013’ (depending on the system setting in the Control Panel)Debug.Print str_lgdt ‘ The result should be: ’09-09-2013’ (depending on the system setting in the Control Panel)Debug.Print str_lgdt ‘ The result should be : 09. September 2013 (depending on the system setting in the Control Panel).

Completion
The formatting function can be widely used to display data (strings, numbers or a combination of both) as we wish. There may be scripts that use queries to store or retrieve data from the backend and compare it to other data displayed on custom forms or web pages.
These comparisons can lead to errors even when the data match, simply because the format of the compared data is different. In such situations, it is useful to use the Format function and convert the data, which is then compared to a common format. This will give you more reliable results.
frequently asked questions
How do I create a function in VBA?
Can I use VBA functions?
You can use VBA functions in any program that supports VBA (including Microsoft Word and Access). Spreadsheet functions are specific to Excel. These are features you already know from spreadsheets – like CONTEXTCENT, COMBIN and VLOCKUP.
How do I walk through a VBA function?
This can be done by pressing the F8 key or by choosing Step from the Debug menu. Each time you select a step, the debugger moves to the next line of code.
