Excel Cheat Sheet
Formulas, functions and formatting, so spreadsheets stop being a mystery.

Basic terms
The most important terms before you get into formulas.
CellA single field, addressed by column and row, for example A1WorksheetA single table within a fileWorkbookThe whole file, can contain several worksheetsCell referenceA reference to another cell, for example =A1+A2Formula basics
Every formula starts with an equals sign.
=A1+A2Adds the values of two cellsRelative referenceA1 automatically adjusts when the formula is copied to other cellsAbsolute reference$A$1 stays the same when copied, toggle it with F4AutoFillDrag the small square at the bottom right of a cell to copy a formula across multiple rowsCommon functions
Ready made functions for the most frequent tasks, each with an example you can check yourself.
SUM(A1:A10)Adds up all the values in a range. Example: A1=2, A2=3, A3=5 → SUM(A1:A3) = 10AVERAGE(A1:A10)Calculates the average of a range. Example: A1=2, A2=4, A3=6 → AVERAGE(A1:A3) = 4IF(A1>10,"big","small")Checks a condition and returns a different value depending on the result. Example: A1=15 → result "big", A1=5 → result "small"VLOOKUPLooks up a value in a table and returns a matching value from another column. Example: if A1:B3 contains the row "Apple,1.20", =VLOOKUP("Apple",A1:B3,2,0) returns 1.2COUNT(A1:A10)Counts how many cells in a range contain a number. Example: A1=5, A2="Text", A3=8 → COUNT(A1:A3) = 2COUNTIF(A1:A10,">10")Only counts the cells in a range that meet a condition. Example: A1=5, A2=12, A3=20 → COUNTIF(A1:A3,">10") = 2SUMIF(A1:A10,">10",B1:B10)Only adds up the values whose matching cell meets a condition. Example: A1=5, A2=12, B1=100, B2=200 → SUMIF(A1:A2,">10",B1:B2) = 200Nested IFSeveral IF functions inside each other, to cover more than two possible outcomes. Example: =IF(A1>=90,"Great",IF(A1>=50,"Passed","Failed")), with A1=70 the result is "Passed"Formatting
So a spreadsheet actually stays readable.
Format cellsSet number format, currency, date or percentage for a cellConditional formattingAutomatically color cells when they meet a certain conditionMerge cellsCombines several cells into one large one, often used for headingsAuto fit column widthDouble click the border between two column headers to fit the width automaticallyCharts and sorting
Evaluate data and present it clearly.
Insert a chartSelect a range, then pick a suitable chart type from the menuSortSort a column ascending or descending without mixing up the rowsFilterOnly show rows that meet a certain conditionFreeze top rowKeeps the header row visible while scrollingData validation and protection
Avoid input mistakes and protect important areas.
Data validationOnly allows certain values in a cell, for example a dropdown list to pick fromProtect sheetPrevents important formulas or values from being accidentally overwrittenInsert commentLeaves a note on a cell without changing its actual contentPivot tables
Quickly summarize and analyze large amounts of data.
Pivot tableAutomatically summarizes large datasets, for example a sum per categoryDrag and dropDrag fields into rows, columns or values with the mouse to change the analysisRefreshAfter changing the source data, the pivot table needs to be refreshed manuallyCommon error values
What these messages in a cell actually mean.
#DIV/0!Division by zero, usually because a referenced cell is empty or zero#N/ANot available, a searched value wasn't found, common with VLOOKUP#NAME?Excel doesn't recognize a function name, often a typoVLOOKUP in detail
Looks up a value in the first column of a range and returns a matching value from another column.
=VLOOKUP(value,range,column_index,0)The 0 at the end forces an exact instead of an approximate matchColumn indexCounts the columns of the search range from 1, not the columns of the whole sheetSortingWithout the 0, the search range needs to be sorted ascending, otherwise the function returns wrong results#N/AAppears when the searched value doesn't exist in the search range at allPercentages
Percentages are just regular numbers internally in Excel, only the display is different.
Percentage formatAutomatically displays 0.2 as 20%, the calculation still uses 0.2Calculate a share=Part/Total, for example =B1/B2 for the percentage sharePercentage change=(New-Old)/Old, a positive result means an increase, a negative one a decreaseFinding cells
Searching a large spreadsheet by hand wastes time.
Ctrl + FOpens a search for a specific value or textCtrl + HOpens find and replace, automatically swaps out found valuesCtrl + GOpens go to, jumps directly to a specific cell addressKeyboard shortcuts
The combinations that save the most time day to day.
