Today I learned how Excel handles decision-making using logical functions:
โข IF โ Test a condition and return results
โข AND โ
๐งต
TRUE only if all conditions are met
โข OR โ TRUE if at least one condition is met
โข NOT โ Reverses a logical result
โข IFS โ Cleaner alternative to nested IF statements
๐๐ข๐ ๐ญ๐๐ค๐๐๐ฐ๐๐ฒ:
Analysis is not just about numbers.
Count non-empty cells
โข COUNTBLANK โ Count empty cells
โข AVERAGE โ Find the mean
โข MIN / MAX โ Find smallest & largest values
โข SMALL / LARGE โ Find nth smallest or largest
๐๐ข๐ ๐ญ๐๐ค๐๐๐ฐ๐๐ฒ:
Great analysis starts with accurate calculations.
Master the basics.

Today I learned how to structure and extract insights using:
โข SORT โ Organize data (AโZ, smallest to largest, newest to oldest)
โข FILTER โ Display only data
๐งต
that meets specific criteria
โข Advanced Filter โ Apply complex criteria and extract unique or refined datasets
๐๐ข๐ ๐ญ๐๐ค๐๐๐ฐ๐๐ฒ:
You cannot analyze what you cannot organize.
SORT brings order.
FILTER brings focus.
Advanced Filter brings control.

Today I learned how to find and replace text more precisely in Excel.
Hereโs what I explored:
โข FIND โ Returns position of a character in a text (case-sensitive)
๐งต
โข SEARCH โ Returns position of a character in a text (not case-sensitive)
โข REPLACE โ Replaces text by position
โข SUBSTITUTE โ Replaces matching text (can replace all or specific occurrences, case-sensitive)

Cleaning data is about control.

Today I learned how powerful text functions are for data cleaning.
In real datasets, text is rarely perfect. Extra spaces, mixed formats, embedded codes, itโs messy.
๐งต
Hereโs what I implemented:
โข LEFT() โ Extract from the beginning
โข RIGHT() โ Extract from the end
โข MID() โ Extract from a specific position
โขTRIM() โ Remove extra spaces
โข LEN() โ Count characters
Example:
=LEFT("Hello", 2) โ "He"
=TRIM(" Hello ") โ "Hello"
