My strategy to learn excel

1) Cover up the most used formulas

SUMIFS
VLOOKUP
XLOOKUP
IFS
IF
COUNTIFS
SUMIF
COUNTIF
INDEX
MATCH
COMBINATION OF INDEX MATCH
CONCATENATE
LEFT
RIGHT
PLAYING WITH DATE FORMATS

2) pick a case study and design some kpi and build a monthly view dashboard by just using formulas

3) Now learn pivots , and build calculated fields with it and build the same view as you done with the formulas

4) Learn power query and data modelling , learn to clean and transformation of data

5) build 3 to 5 projects on excel to get super confidence

4 reasons why you should start your analytics journey with Excel.

1) It's the Swiss Army Knife of data
- Clean data
- Ad-hoc analytics
- Create visualizations
- Automations (Macros)

2) Integration with other tools
- Excel spreadsheets feed data into everything
- MS Access, Tableau, Power BI, SQL, etc

3) Power BI adoption
- DAX and Power Query in Excel make PBI easier to adopt

4) All roads lead back to Excel eventually (trust me)
- As hard as you try, you can never escape it

There's much more to learn after Excel, but starting here will create a strong foundation for your analytics career path!

Top 10 Excel Functions Used by Data Analysts

1. VLOOKUP:
• Example: =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
• Usage: Searches for a value in the first column of a table and returns a value in the same row from another column.

2. HLOOKUP:
• Example: =HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])
• Usage: Similar to VLOOKUP, but searches in the first row of a table.

3. INDEX-MATCH:
• Example: =INDEX(return_range, MATCH(lookup_value, lookup_range, 0))
• Usage: A more flexible alternative to VLOOKUP or HLOOKUP for lookups.

4. SUMIFS:
• Example: =SUMIFS(sum_range, criteria_range1, criteria1, [criteria_range2, criteria2, ...])
• Usage: Adds values based on multiple criteria.

5. COUNTIFS:
• Example: =COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2, ...])
• Usage: Counts cells based on multiple criteria.

6. AVERAGEIFS:
• Example: =AVERAGEIFS(average_range, criteria_range1, criteria1, [criteria_range2, criteria2, ...])
• Usage: Calculates the average based on multiple criteria.

7. CONCATENATE:
• Example: =CONCATENATE(text1, [text2, ...]) or =text1 & [text2]
• Usage: Combines text from multiple cells into one cell.

8. IF:
• Example: =IF(logical_test, value_if_true, value_if_false)
• Usage: Performs conditional logic based on a specified condition.

9. PivotTables:
• Usage: Allows for dynamic data summarization and analysis in a table format.

10. SUM, AVERAGE, COUNT:
• Examples: =SUM(range), =AVERAGE(range), =COUNT(range)
