xxxxxxxxxx- Filtering : `=FILTER(A2:H20,H2:H20=TRUE)` (Only return result of A2 to H20 if the condifition of H2 to H20 is true)- Checking data-type: `=ISNUMBER(A1)`, `"=ISTEXT(A1)`, `=ISDATE(A1)`, `=ISLOGICAL(A1)`, `=ISURL(A1)`, `=ISFORMULA(A1)`- converting to other data-type : `=TO_DOLLARS(A1)`, `=TO_PERCENT(A1)`, `=N(A1)`- convert to another unit : `=CONVERT(A1,"ft^2","m^2")`- If-else : `=IF(A1,1,0)`- To make the text into a clickable hyperlink: `=HYPERLINK(A1,B1)` (Show content of B1 but it is a link that contains A1 hyperlink)- Transformation of log (10-based), log (e-based), power, exponential, square-root : `=LOG10(A1)`, `=LN(A1)`,`=10^A1`, `=EXP(A1)`, `=SQRT(A1)`- rounding transformation : `=ROUND(A1, 2)`, `=ROUND(A1, -2)`, `=CEILING(A1,100)`, `=FLOOR(A1,100)`- random numbers: `=RAND()`, `=RANDBETWEEN(-10,10)`- produce RANDOM numbers for given distribution: `=NORMINV(RAND(),0,1)`, `=LOGINV(RAND(),0,1)`, `=TINV(RAND(),5)`, `=FISHERINV(RAND())`, `=FINV(RAND(),2,2)`, `=BETAINV(RAND(),1,1,-10,10)`- Logical NOT, AND, OR : `=NOT(A1)`, `=AND(A1,A2)` , `=OR(A1,A2)`- Single condition (if and else): `= IF(A3>3, "if_true_then_this","if_false_then_this")`- Multiple condition (multiple if, no else, `#N/A` if no condition met): `= IFS(A1, "if_A1_then_this",A2,"if_A2_then_this")`- Switch transformation (transform categorical variables into numerical, `#N/A` if no match found): `=SWITCH(A1,"JAN",1,"FEB",2)`- Check Blank, count blank : `=ISBLANK(A1)`, `=COUNTBLANK(A1:A10)`- Correct way to compute with blank (if blank, then `#N/A` ERROR, else OK, then count): `=IF(ISBLANK(A2),NA(),A2)`- Check Error (all errors produced by functions + missing values): `=ISERROR(A1)`- Check Error (all errors produced by functions , Blanks and missing are not errors): `=ISERR(A1)`- Create N/A : `=NA()`- See row value in integer : `=ROW(A5)`- See column value in integer : `=COLUMN(A5)`- Create Absolute Address from row cell and column cell : `=ADDRESS(A1,A2)`- Create Relative Address from row cell and column cell : `=ADDRESS(A1,A2,4)`- Create pointer to redirect cell address: `= INDIRECT(A1)` - go to A1, take the value of A1 as the address of target cell, go to that cell and fetch the value- Date functions: - date to string format : `=TEXT("1/9/2012", "mmmmm-dd-yy")` will make it (J-09-12) - `NOW()`, `TODAY()` : current time and date - `=DATEDIF(start_date, end_date, 'M')` : interval as month- Text functions: - `=UPPER()`, `=PROPER()` ,`=LOWER()`, `=TRIM()`, `=CONCATENATE()`, `=LEN()`, `=LEFT()`, `=RIGHT()` - `=SEARCH(character, text, starting_index)` : Returns the index where the character is located in the text - `=SUBSTITUTE(text, old_substring, new_substring, [occurences])` : Replace a substring inside a text- Conditional Aggregations: - `COUNTIF(A1:A, ">1000")` : count only if A1 to A-downward values are greather than 1000 - `COUNTIFS(range1, "condition1", [range2, condition2] ....)` : `AND` operation on multiple `COUNTIF` - `SUMIF(condition_range, "condition", sum_range)` : check condition in condition_range and sum the adjacent cells in specified range when true - `SUMIFS(sum_range,condition1_range, "condition1",[condition2_range, "condition2"] )` : `AND` operation on multiple `SUMIF` - `AVERAGEIF` and `AVERAGEIFS` : Same as `SUMIF` and `SUMIFS`- Find value of a cell relative to specified cell A1: `=OFFSET(A3,3,1)` - Go to cell A3 - go down 3 cells - go right 1 cell - take that cell's value- Find value of a cell in a matrix / dataset: `=INDEX($A$1:$B$6,3,1)` - Go to cell $A$1, as the starting point of dataset / matrix - go to row no 3 of dataset - go to column no 1 of dataset - take that cell's value- `=VLOOKUP(A1, $A$5:$B$10, 2, FALSE)` (Joining on column) - search value is in A1, - Find where that value matches in whole dataset `$A$5:$B$10` - Take the row of the match in dataset - return the value from second column - `FALSE` means strict match, `TRUE` means any close match to nearest number- `=SORT($A$5:$B$10, 2, FALSE)` - Sort the whole table / dataset by second column - `FALSE` means descending order, `TRUE` means ascending order- `=MATCH(10000, $A$5:$B$10, -1)` - Find 10000 in the whole table / dataset - The dataset is in descending order (-1) or ascending order (1) - returns the position of the value in the sorted order- Other errors: - `#DIV/0!` : Dividing by zero - `#VALUE!` : Nonsense value in calculation - `#REF!` : Reference error - `#NAME?` : Forgetting quote in string - `#NUM!` : Numbers out of range - `#N/A` : Missing value - `#ERROR!` : Syntax in formulaSource: Grepper
