There exist a great lot of Microsoft Excel functions to manipulate text strings espeacily in finance and accounting. Here are the most essential ones:

1-TEXT function

TEXT(value, format_text) is used to convert a number or a date into a test string in the specified format, where:

• Value is a numeric value you want to convert to text.
• Format_text is the desired format.

The following formulas demonstrate the Excel TEXT function in action:

=TEXT(A1,"mm/dd/yyyy") - convert a date in cell A1 into a text string in the traditional US date format, such as "01/01/2015" (month/day/year).

=TEXT(A1,"€#,##0.00") - converts a number in A1 into a currency text string such as "€3.00".

2-TRIM function

TRIM(text) removes leading, trailing spaces as well as excess spaces between words. Where textis either a text string or reference to the cell containing the text from which you want to remove spaces. The following screenshot demonstrates an example of usage:

3-SUBSTITUTE function

SUBSTITUTE(text, old_text, new_text, [instance_num]) replaces one set of characters with another in a specified cell or a text string. The syntax of the SUBSTITUTE function is as follows:

• Text - the original text string or reference to a cell where you want to substitute certain characters.
• Old_text - the characters you want to replace.
• New_text - the characters you want to replace the old text with.
• Nth_appearance - an optional parameter that specifies which occurrence of old_text you want to replace with new_text. If omitted, then every occurrence of the old text will be replaced with the new text.

For example, the following SUBSTITUTE formula replaces all commas in cell A1 with semicolons:

=SUBSTITUTE(A2, ",", ";")

4-VALUE function

VALUE(text) - converts a text string to a number.

This function is really helpful when it comes to converting text-formatted values representing the numbers into numbers that can be used in other Excel formulas and calculations.

5-EXACT function

EXACT(text1, text2) compares two text strings and returns TRUE if both values are exactly the same, including case, FALSE otherwise.

For example, if A2 is "apples" and B2 is "Apples", the formula =EXACT(A2, B2) will returns FALSE, because they are not exact match.

I also agree with the experts answers.

Round is the most common and important function in MS Excel to round figure the amount.

thanks for the invitation and keep it up.

I am agree with ghada ewada , and Moin Akber.......
