    Introduction to Excel Formulas and Functions

    Formulas in Excel are expressions that perform calculations on values in your worksheet. Every formula starts with an equal sign (=). Functions are predefined formulas that simplify complex calculations.

    For example:

    • A simple formula: =A1 + B1 adds the values in cells A1 and B1.
    • A function: =SUM(A1:A10) adds a range of cells.

    Excel follows the order of operations (PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction). Use parentheses to control the order, like =(A1 + B1) * C1.

    In 2025, Excel includes enhanced AI features like Copilot, which can suggest or generate formulas automatically.

    Basic Arithmetic and Math Functions

    Start with the basics to build confidence.

    Common operators:

    • Addition: +
    • Subtraction: –
    • Multiplication: *
    • Division: /
    • Exponentiation: ^

    Essential math functions:

    • SUM: =SUM(A1:A10) – Adds numbers in a range.
    • AVERAGE: =AVERAGE(A1:A10) – Calculates the mean.
    • MIN and MAX: Finds the smallest/largest value.
    • COUNT: =COUNT(A1:A10) – Counts numeric entries.
    • COUNTA: Counts non-empty cells.
    • ROUND: =ROUND(number, num_digits) – Rounds to specified decimals.

    Example: To calculate total sales tax: =SUM(B2:B10) * 0.08.

    These functions handle everyday tasks like budgeting or grading.

    Logical Functions for Decision-Making

    Logical functions allow conditional calculations.

    • IF: =IF(logical_test, value_if_true, value_if_false) Example: =IF(A1 > 100, “Bonus”, “No Bonus”) – Checks if sales exceed 100.
    • AND and OR: Combine conditions. =IF(AND(A1>100, B1=”Yes”), “Approved”, “Denied”)
    • IFERROR: Handles errors gracefully: =IFERROR(A1/B1, “Divide by zero”)
    • Nested IFs: For multiple conditions, though IFS (below) is better.

    Newer: IFS for multiple conditions: =IFS(A1>90, “A”, A1>80, “B”, TRUE, “F”)

    These are crucial for dashboards and reports.

    Lookup and Reference Functions

    Lookup functions find data in tables.

    • VLOOKUP: Searches vertically. =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
    • XLOOKUP (recommended in 2025): More flexible, searches any direction. =XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found])
    • INDEX and MATCH: Powerful combination for dynamic lookups. =INDEX(range, MATCH(lookup_value, lookup_column, 0))

    Use these for merging data from different sheets or databases.

    Text Functions for Data Cleaning

    Text manipulation is common for cleaning imported data.

    • CONCAT or TEXTJOIN: Combine text. =TEXTJOIN(” “, TRUE, A1, B1, C1)
    • LEFT, RIGHT, MID: Extract substrings. =LEFT(A1, 3) – First 3 characters.
    • TRIM: Removes extra spaces.
    • UPPER, LOWER, PROPER: Change case.
    • FIND or SEARCH: Locate text position.

    In 2025, new REGEX functions allow advanced pattern matching.

    Date and Time Functions

    Handle dates effortlessly.

    • TODAY() and NOW(): Current date/time.
    • DATE: =DATE(year, month, day)
    • DATEDIF: Calculate differences: =DATEDIF(start_date, end_date, “Y”) for years.
    • EOMONTH: End of month.
    • WORKDAY: Add business days.

    Example: Age calculation: =DATEDIF(B2, TODAY(), “Y”)

    Statistical and Aggregation Functions

    For data analysis:

    • SUMIF and SUMIFS: Conditional sums. =SUMIFS(sum_range, criteria_range1, criteria1, …)
    • COUNTIF and COUNTIFS: Conditional counts.
    • AVERAGEIF and AVERAGEIFS.

    These are foundational for summaries.

    Advanced Functions

    Go beyond basics:

    • LET: Name calculations for readability. =LET(total, SUM(A1:A10), total * 1.1)
    • LAMBDA: Create custom functions.
    • Dynamic arrays: FILTER, SORT, UNIQUE – Spill results automatically. Example: =FILTER(A1:B10, B1:B10 > 100)
    • SCAN: For running totals.

    In 2025, Python integration allows advanced analytics directly in Excel.

    Working with PivotTables

    PivotTables summarize large datasets without formulas.

    Steps:

    1. Select data.
    2. Insert > PivotTable.
    3. Drag fields to Rows, Columns, Values, Filters.

    Essential Tips and Tricks

    Boost productivity:

    • Keyboard Shortcuts:
      • Ctrl + Shift + L: Toggle filters.
      • Alt + =: AutoSum.
      • F4: Toggle absolute/relative references.
      • Ctrl + Arrow: Jump to edge.
    • Flash Fill: Auto-detect patterns (Ctrl + E).
    • Freeze Panes: View > Freeze Panes for headers.
    • Data Validation: Restrict inputs.
    • Conditional Formatting: Highlight rules.
    • Absolute vs Relative References: $A$1 (absolute), A1 (relative).
    • Name Ranges: Formulas > Name Manager for readability.
    • Error Checking: Trace precedents/arrows.
    • Quick Analysis: Ctrl + Q for charts/formats.

    Avoid common pitfalls: #DIV/0!, #REF!, circular references.
