switch functions

  Nested IF Function : The  nested IF  function allows you to perform tests with multiple conditions and return different values based on the results of those tests. It is called “nested” because one IF function is embedded inside another IF function. Syntax of a generic nested IF formula: =IF(condition1, result1, IF(condition2, result2, IF(condition3, result3, result4) ) ) Each subsequent IF function is embedded into the  value_if_false  argument of the previous function. SWITCH Function : The  SWITCH  function is a more compact alternative to nested IF statements. It compares an expression against a list of values and returns the result according to the first matching value. Syntax of the SWITCH function: =SWITCH(expression, value1, result1, [default or value2, result2], ... [default or valueN, resultN]) It has four arguments: expression : The value to compare against the list of values. valueN : A value com...

LEFT : Syntax: =LEFT(text, num_chars) Example: =LEFT(A1, 3) Returns a specified number of characters from the beginning of a text string. RIGHT : Syntax: =RIGHT(text, num_chars) Example: =RIGHT(A1, 3) Returns a specified number of characters from the end of a text string.
