Spreadsheet basics

What is a Spreadsheet?

Definition and components

A spreadsheet is a grid-based tool used to organize, compute, and analyze data. It consists of cells arranged in rows and columns, with each cell holding a value, text, or a formula. The grid is complemented by elements such as headers, borders, and formatting options that help clarify data. Spreadsheets also support charts, sorting, filtering, and a variety of functions that automate calculations, making it easier to derive insights from raw numbers.

Workbook vs Worksheet

A workbook is the file that contains one or more worksheets. Think of it as a binder of pages; each page is a worksheet where you enter and manipulate data. Worksheets are individual sheets within the workbook, each with its own grid and tab for navigation. You can switch between sheets to organize related data, analyses, or versions of a project without opening separate files.

Spreadsheet Basics

Cells and ranges

A cell is the intersection of a column and a row, identified by a reference such as A1 or D12. A range is a block of contiguous cells, like A1:C5, and it can be used in formulas to perform calculations on a group of values. Relative references (A1) adjust when you copy formulas, while absolute references ($A$1) stay fixed. Named ranges provide a readable alias for a set of cells, improving clarity in complex workbooks.

Workbook structure and navigation

Workbooks organize related data across multiple worksheets. Navigation is typically done via sheet tabs, which let you switch views quickly. Within a worksheet, you move with arrow keys or click to select cells. You can jump to the ends of data using keyboard shortcuts, select entire rows or columns, and resize columns to fit content. A well-structured workbook keeps data, calculations, and results logically separated yet easy to trace.

Getting Data In

Manual data entry tips

Manual entry should be deliberate and tidy. Start with clear headers, keep data in uniform formats, and use a consistent row order. Use the Tab key to move horizontally and Enter to move to the next row. Where possible, rely on lists and data validation to minimize inconsistent entries, and keep a clean data layout to simplify later analysis.

Importing data from external sources

External data can be brought in via CSV, Excel imports, database connections, or by copying and pasting. When importing, verify data types (numbers, dates, text), align columns with your target sheet, and check for encoding issues. After import, scan for anomalies, remove duplicates if needed, and consider placing raw data on a separate sheet to preserve a clean working view.

Formatting for Clarity

Number formats (currency, date)

Number formatting makes data readable at a glance. Use currency formats for monetary values, including the appropriate symbol and decimal places. Date formats help ensure consistent interpretation across regions. Choosing a standard format for numbers and dates reduces confusion and improves consistency when you share the sheet.

Text alignment and cell styles

Align text to improve readability: left alignment for most data, right alignment for numbers, centered headers for emphasis. Wrap text to prevent overflow, and apply cell styles such as bold or italic for headings and highlights. Simple borders and shading can help distinguish sections without distracting from the data.

Formulas and Functions

What is a formula?

A formula is an expression that computes a value. It always starts with an equals sign (=) and can reference other cells, use operators, and call functions. Formulas recalculate automatically when inputs change, which makes it easy to keep results up to date as data evolves. Mastery of relative and absolute references is key for copying formulas across a range of cells.

Common functions (SUM, AVERAGE, IF)

Common functions simplify everyday calculations. SUM adds numbers in a range, such as =SUM(A1:A10). AVERAGE computes the mean of a range, like =AVERAGE(B1:B10). IF enables conditional logic, for example =IF(C1>0,”Positive”,”Non-positive”), returning different results based on a test. Combining functions can handle more complex scenarios and automate decision rules.

Data Management

Sorting and filtering data

Sorting rearranges rows based on the values in a selected column, either ascending or descending. Filtering hides rows that don’t meet specified criteria, allowing you to focus on a subset of data without deleting anything. Together, sorting and filtering help you explore patterns, compare groups, and prepare data for reporting.

Data validation and data cleaning

Data validation restricts inputs to acceptable values, such as numeric ranges or predefined lists, reducing errors at entry. Data cleaning includes removing duplicates, trimming extra spaces, standardizing formats, and correcting inconsistent terms. Regular data hygiene improves accuracy and reliability of analyses drawn from the sheet.

Charts and Visualizations

Choosing chart types

Chart type should reflect the story you want to tell. Line charts show trends over time; bar or column charts compare quantities across categories; pie and donut charts illustrate composition; scatter plots reveal relationships between two variables. Favor simplicity and avoid clutter to ensure the chart communicates clearly.

Creating and formatting charts

To create a chart, select the relevant data and insert the appropriate chart. Customize titles, axis labels, and legends for clarity. Adjust colors for contrast and accessibility, and add data labels when they help interpretation. Place charts near the data they summarize or in a dedicated dashboard for a concise overview.

Productivity Shortcuts

Navigation shortcuts

Efficient navigation saves time. Use arrow keys to move cell by cell, Tab/Shift+Tab to move horizontally, and Ctrl+Arrow to jump to the edge of data. Page Up/Page Down and Home/End accelerate movement within large sheets. Being fluent with these shortcuts reduces distractions and speeds up tasks.

Editing and autofill tricks

F2 edits the active cell, and Enter commits changes. The fill handle (the small square at the bottom-right of a selection) lets you extend patterns or data sequences quickly. Shortcuts like Ctrl+D (fill down) and Ctrl+R (fill right) automate repetitive entry, while a well-used Flash Fill feature can infer patterns in data entry across rows.

Key takeaway

Education data from Our World in Data highlight persistent gaps in access and attainment across regions and income levels. Clear, comparable data visualizations enable policymakers and educators to spot trends, allocate resources efficiently, and monitor progress toward education goals.
