This document provides a detailed and practical explanation of Object-Oriented Programming (OOP) concepts—Abstraction, Encapsulation, Inheritance, and Polymorphism—across three popular platforms: C++, Python, and Selenium. It is ideal for learners at the beginner to intermediate level who want to understand how OOP is implemented in both programming and automation frameworks. The content includes theoretical explanations, syntax comparisons, real-world examples, and code snippets for each concept in C++ and Python, along with a special section on how OOP principles are applied in Selenium using the Page Object Model (POM). Compiled in 2024, this resource is suitable for students, software developers, and QA engineers, and has been authored by Rachel Hephizibah as part of a self-paced course in software development and automation testing.

# [ Excel Advanced Functions and Formulas ] CheatSheet



1. Advanced Lookup Functions

● Index-Match: =INDEX(return_range,MATCH(lookup_value,lookup_range,0))
● Double Index-Match:
=INDEX(return_range,MATCH(row_value,row_lookup,0),MATCH(col_value,c
ol_lookup,0))
● Multi-criteria Index-Match:
=INDEX(return_range,MATCH(1,(criteria1=range1)*(criteria2=range2),0
))
● Offset-Match:
=OFFSET(reference,MATCH(lookup_value,lookup_range,0)-1,0)
● Xlookup basic: =XLOOKUP(lookup_value,lookup_array,return_array)
● Xlookup with not found:
=XLOOKUP(lookup_value,lookup_array,return_array,"Not Found")
● Xlookup exact match:
=XLOOKUP(lookup_value,lookup_array,return_array,,-1)
● Xlookup wildcard:
=XLOOKUP("*"&lookup_value,lookup_array,return_array)
● Xlookup multiple returns:
=XLOOKUP(lookup_value,lookup_array,{return_array1,return_array2})
● Xlookup reverse lookup:
=XLOOKUP(lookup_value,lookup_array,return_array,,,-1)

2. Array Formulas

● Sum array: =SUM(IF(criteria_range=criteria,sum_range))
● Count array: =SUM(IF(criteria_range=criteria,1))
● Average array: =AVERAGE(IF(criteria_range=criteria,average_range))
● Multi-condition array:
=SUM(IF((criteria1_range=criteria1)*(criteria2_range=criteria2),sum
_range))
● Unique values array: =UNIQUE(range)
● Sort array: =SORT(range,[sort_column],[sort_order],by_col)
● Filter array: =FILTER(range,criteria_range=criteria)
● Sequence generation: =SEQUENCE(rows,[columns],[start],[step])
● Array spill: =range#
● Dynamic array expansion: =INDIRECT("A1:A"&COUNTA(A:A))

, 3. Text Functions

● Extract first word: =LEFT(A1,FIND(" ",A1&" ")-1)
● Extract last word: =RIGHT(A1,LEN(A1)-FIND("~",SUBSTITUTE(A1,"
","~",LEN(A1)-LEN(SUBSTITUTE(A1," ","")))))
● Extract nth word: =TRIM(MID(SUBSTITUTE(A1," ",REPT("
",100)),((n-1)*100)+1,100))
● Case-sensitive find: =FIND(find_text,within_text)
● Case-insensitive find: =SEARCH(find_text,within_text)
● Replace multiple instances:
=SUBSTITUTE(text,old_text,new_text,instance_num)
● Clean text: =CLEAN(TRIM(text))
● Proper case with exceptions: =IF(ISNUMBER(SEARCH("
mc",LOWER(A1))),PROPER(A1),PROPER(SUBSTITUTE(A1," mc"," Mc")))
● Remove special characters: =REGEXREPLACE(A1,"[^a-zA-Z0-9]","")
● Extract numbers from text: =--REGEXREPLACE(A1,"[^0-9.]","")

4. Date and Time Functions

● Last day of month: =EOMONTH(date,0)
● First day of month: =EOMONTH(date,-1)+1
● First day of next month: =EOMONTH(date,0)+1
● Next occurrence of day: =date+MOD(target_day-WEEKDAY(date),7)
● Working days calculation: =NETWORKDAYS(start_date,end_date,holidays)
● Add working days: =WORKDAY(start_date,num_days,holidays)
● Fiscal year start:
=DATE(YEAR(date)+(MONTH(date)>fiscal_month),fiscal_month,1)
● Quarter from date: =ROUNDUP(MONTH(date)/3,0)
● Week number: =WEEKNUM(date,[return_type])
● ISO week number: =ISOWEEKNUM(date)

5. Math and Statistical Functions

● Weighted average: =SUMPRODUCT(range,weights)/SUM(weights)
● Percentile calculation: =PERCENTILE.INC(range,k)
● Mode multiple values: =MODE.MULT(range)
● Median excluding zeros: =MEDIAN(IF(range<>0,range))
● Moving average: =AVERAGE(OFFSET(cell,0,0,n,1))
● Exponential moving average: =α*current+(1-α)*previous
● Standard deviation sample: =STDEV.S(range)
