Workbook

The file that holds one or more worksheets in a spreadsheet program. It stores all sheets, formulas, charts, and formatting together, and is saved under a single filename.

Related: Worksheet, Cell Reference
Worksheet

A single grid of rows and columns inside a workbook where data is entered and calculated. Each worksheet has its own tab name and can be referenced by formulas in other sheets.

Related: Workbook, Active Cell
Active Cell

The currently selected cell that receives typed input and shows a highlighted border. Its address appears in the Name Box, and its stored content appears in the Formula Bar.

Related: Name Box, Formula Bar
Name Box

The small field left of the Formula Bar that displays the address or defined name of the selected cell or range. Typing an address there jumps directly to that location.

Related: Active Cell, Named Range
Formula Bar

The input line near the top of the window that shows the underlying content of the active cell, including formulas rather than their results. Edits can be made there directly.

Related: Active Cell, Formula
Cell Reference

The address of a cell formed by its column letter and row number, such as B7. References let formulas use values stored elsewhere instead of hard-coded numbers.

Related: Absolute Reference, Relative Reference
Relative Reference

A cell address like A1 that shifts automatically when a formula is copied to another row or column. It keeps the formula pointing at the same positional offset from its new location.

Related: Absolute Reference, Mixed Reference
Absolute Reference

A cell address locked with dollar signs, such as $A$1, so it does not change when the formula is copied or filled. Used to anchor a constant rate, table, or lookup source.

Related: Relative Reference, Mixed Reference
Mixed Reference

A reference where only the column or only the row is locked, written as $A1 or A$1. Copying the formula adjusts the unlocked part while the locked part stays fixed.

Related: Absolute Reference, Relative Reference
Named Range

A descriptive label assigned to a cell or range so formulas can refer to it by name, such as TaxRate, instead of an address. Names make formulas easier to read and maintain.

Related: Name Box, Cell Reference
Formula

An expression beginning with an equals sign that calculates a result from values, cell references, and operators. The cell displays the result while the Formula Bar shows the expression.

Related: Function, Operator Precedence
Function

A built-in named routine that performs a calculation on supplied arguments, such as SUM or VLOOKUP. Functions are called inside formulas with parentheses around their arguments.

Related: Formula, Argument
Argument

A value, cell reference, range, or text string passed to a function inside its parentheses. Arguments are separated by commas or semicolons depending on regional settings.

Related: Function, Syntax Error
Operator Precedence

The fixed order in which a spreadsheet evaluates arithmetic operators, with exponentiation first, then multiplication and division, then addition and subtraction. Parentheses override this default order.

Related: Formula, Error Value
Error Value

A code such as #DIV/0!, #REF!, #VALUE!, or #N/A that appears when a formula cannot produce a valid result. Each code points to a specific cause such as division by zero or a broken reference.

Related: Syntax Error, Formula
Syntax Error

A mistake in the structure of a formula, such as unbalanced parentheses or a missing argument separator, that prevents the spreadsheet from accepting the entry. It is usually flagged immediately on entry.

Related: Error Value, Argument
Fill Handle

The small square at the lower-right corner of a selection that, when dragged, copies or extends content. It continues series patterns and adjusts relative references in formulas.

Related: Relative Reference, AutoFill Series
AutoFill Series

The pattern a spreadsheet recognizes and continues when the Fill Handle is dragged, such as months, weekdays, or numbered sequences. Custom lists can be defined to extend it.

Related: Fill Handle
Freeze Panes

A view setting that locks chosen rows or columns in place so they stay visible while scrolling through the rest of the sheet. Commonly used to keep header rows on screen.

Related: Worksheet, Print Area
Print Area

The specific range of cells designated for printing, so surrounding data is excluded from output. It can be set, changed, or cleared for each worksheet.

Related: Freeze Panes, Page Break
Page Break

A manual or automatic division that determines where a printed worksheet starts a new page. Manual breaks override the automatic pagination the program calculates.

Related: Print Area
Conditional Formatting

A rule-based feature that changes a cell's appearance, such as fill color or icon, when its value meets a specified condition. It highlights trends and exceptions without altering the underlying data.

Related: Data Validation, Data Bar
Data Validation

A rule that restricts what can be entered into a cell, such as a list of allowed values or a numeric range. It can also display an input message or an error alert.

Related: Conditional Formatting, Lookup Table
Data Bar

A conditional formatting style that draws a horizontal bar inside a cell whose length reflects the value relative to other cells in the range. It gives an in-cell visual comparison.

Related: Conditional Formatting, Sparkline
Sparkline

A tiny chart drawn inside a single cell that summarizes a row or column of values as a line, column, or win-loss display. It shows trend at a glance without a full chart object.

Related: Data Bar, Chart
Chart

A graphical representation of worksheet data, such as a column, line, or pie chart, linked to the source range. Changes to the source data are reflected automatically in the chart.

Related: Data Series, Category Axis
Data Series

The set of values plotted from one row or column of source data, shown as one line, bar set, or slice group. Each series is identified in the chart legend.

Related: Chart, Legend
Category Axis

The axis, usually horizontal, that displays the labels or groupings against which values are plotted. In a column chart it shows the items being compared.

Related: Value Axis, Chart
Value Axis

The axis, usually vertical, that shows the numeric scale of plotted values and is often called the Y axis. Its minimum, maximum, and interval can be set manually.

Related: Category Axis, Chart
Legend

The key on a chart that maps colors or patterns to the data series they represent. It helps readers identify which line or bar corresponds to which data.

Related: Data Series, Chart
PivotTable

An interactive summary table that groups and aggregates large data sets by dragging fields into row, column, value, and filter areas. It recalculates as fields are rearranged.

Related: PivotChart, Slicer
PivotChart

A chart tied to a PivotTable that updates whenever the table's fields or filters change. It visualizes the same summarized values rather than the raw source data.

Related: PivotTable, Chart
Slicer

A floating set of buttons that filters a PivotTable or table with a single click, showing the current selection. It offers a more visual alternative to filter drop-downs.

Related: PivotTable, Filter
What-If Analysis

A set of tools that test how changing input values affects calculated results, including data tables, scenario manager, and goal seek. It answers questions without altering the original data permanently.

Related: Goal Seek, Scenario
Goal Seek

A tool that finds the input value required to make a formula reach a specified target result. It adjusts one variable cell while the formula cell is held at the desired output.

Related: What-If Analysis, Scenario
Scenario

A saved set of alternative input values given a name, so different assumptions can be switched and compared. The Scenario Manager stores and displays these versions side by side.

Related: What-If Analysis, Goal Seek
Lookup Table

A separate range that maps keys to corresponding values, used by lookup functions to retrieve related data. Keeping it separate makes maintenance and validation easier.

Related: Data Validation, Primary Key
Primary Key

A column or set of columns whose values uniquely identify each row in a table. It cannot contain duplicates or nulls, and other tables reference it through foreign keys.

Related: Foreign Key, Relational Database
Foreign Key

A column in one table that holds values matching the primary key of another table, creating a link between them. It enforces referential integrity between related records.

Related: Primary Key, Referential Integrity
Relational Database

A collection of data organized into tables of rows and columns that are linked by shared key values. Relationships reduce duplication and let queries combine data across tables.

Related: Primary Key, Normalization
Normalization

The process of structuring tables to reduce redundant data and avoid update anomalies, typically by splitting data into related tables. It proceeds through numbered normal forms.

Related: Relational Database, Referential Integrity
Referential Integrity

A rule ensuring that every foreign key value matches an existing primary key value, or is null. It prevents orphaned records and keeps relationships consistent.

Related: Foreign Key, Primary Key
SQL

Structured Query Language, the standard language for defining, querying, and modifying data in a relational database. Statements include SELECT, INSERT, UPDATE, and DELETE.

Related: SELECT Statement, JOIN
SELECT Statement

The SQL statement that retrieves rows and columns from one or more tables. Clauses such as WHERE, GROUP BY, and ORDER BY refine which rows return and how they are sorted.

Related: WHERE Clause, JOIN
WHERE Clause

The SQL clause that filters rows, returning only those for which a condition is true. It can combine comparisons and logical operators with AND, OR, and NOT.

Related: SELECT Statement, JOIN
JOIN

A SQL operation that combines rows from two or more tables based on a related column. Inner joins return matches only, while outer joins also keep unmatched rows from one side.

Related: Foreign Key, SELECT Statement
Query

A request that extracts, filters, or summarizes data from tables according to specified criteria. In a database it is written in SQL; in a spreadsheet it can be built graphically.

Related: SELECT Statement, WHERE Clause
