Excel formulas
Cell address
Relative address: Column letter(s) & Row number
Relative address changes during copying
Absolute address: $Column letter(s) & $Row number
Absolute address remain unchanged during copying
Key F4 switches between relative and absolute address
Content of cell can be:
Blank
Numeric value (including date and time)
Text
Logical value (TRUE or FALSE)
Formula (begins with =)
Formula contains mathematical (+,-,*,/,^), logical(=,>,<,<=,>=,<>) or text (&)
operations and/or functions
Cell range
First cell (left-upper):Last cell (right-bottom)
Cells and ranges can have names.
Functions in Excel
Math & Trig functions
SUM(cells range) – sum of numerical data
SUMIF(cells range;condition;values to sum) –
sum of selected values
condition – value or conditional expression (>, <)
*– any number of any characters
ABS(value) – absolute value
INT(value) – integer part of value
ROUND(value;number of digits) – rounded value
RAND() – random number in range 0...1
RANDBETWEEN(min;max) – random integer number between min and max
Trigonometric functions – PI, SIN, COS, TAN, ASIN, ACOS, ATAN
Statistical functions
Empty cells and cells with non-numeric values are mostly ignored.
MIN(cells range) – minimal value
MAX(cells range) – maximum value
AVERAGE(cells range) – average of values
COUNT(cells range) – number of cells with numeric value
COUNTA(cells range) – number of non-empty cells
COUNTBLANK(cells range) – number of empty cells
COUNTIF(cells range;condition) – number of cells satisfying condition
COUNTIFS(cells range1;condition1;cells range2;condition2;...) – number of cells satisfying
all conditions
RANK.EQ(value;cells range) – place (rank) of value in range of values
LARGE(cells range;position) – value in specified position (descending sequence)
SMALL(cells range;position) – value in specified position (ascending sequence)
MODE.SNGL(cells range) – most frequently occurring value (#N/A, if missing)
Date & Time functions
Date-Time-value
Integer part – number of days from 1. January 1900
Decimal part – part of day, used for time
Formatting shows Date-Time-value differently, but don’t change its value!
TODAY() – computer date
NOW() – computer date and time
DATE(year;month;day) – creating Date-Time-value (Date part)
TIME(hour;minute;second) – creating Date-Time-value (Time part)
YEAR(Date-Time-value)
MONTH(Date-Time-value)
DAY(Date-Time-value)
HOUR(Date-Time-value)
MINUTE(Date-Time-value)
SECOND(Date-Time-value)
WEEKDAY(Date-Time-value;2) – weekday (1=Monday)
DAYS360(Date-Time-value1, Date-Time-value2) – Difference in days, using 360-days
system (12 months, 30 days in every month)
EDATE(Date-Time-value;months) – adding months to date
EOMONTH(Date-Time-value;months) – last day in month
NETWORKDAYS – number of workdays, excluding holidays
WORKDAY – adding workdays, excluding holidays
YEARFRAC – difference of two dates in years
Lookup functions
Search (lookup) table
First column – values for lookup
Other columns – search values
VLOOKUP(lookup value;cells range of lookup table;number of column;search mode)
Mode TRUE (default) – range search,
Mode FALSE – search of exact value.
HLOOKUP – search from horizontal lookup table
CHOOSE(index;array) – choose from array of values
MATCH(value;range;mode) – index (position) of value in the range; mode=0 – exact match
INDEX(range;row_num;column_num) – value in range of cells
Logical functions
IF(condition;formula if true;formula if false) – formula depends on condition
IFERROR(formula, if formula value is error)
IFNA(formula, if formula value is #N/A)
AND, OR, NOT – logical operations
TRUE, FALSE – logical values
Information functions
