Excel Spreadsheet Fundamentals

An Excel spreadsheet is organized around a few core elements. A workbook is the entire file—saved as .xlsx—and it contains one or more worksheets (tabs visible at the bottom of the screen). Each worksheet is a grid of cells organized into columns (identified by letters: A, B, C...) and rows (identified by numbers: 1, 2, 3...). A cell is the intersection of a column and a row, identified by its address such as B3. The Name Box at the top left shows the currently selected cell's address, and the Formula Bar next to it shows its contents. The Ribbon at the top contains all commands organized into tabs (Home, Insert, Page Layout, Formulas, Data, Review, View). You can navigate cells with arrow keys, Tab (move right), Enter (move down), or by clicking. Pressing Ctrl+Home returns to cell A1. Ctrl+End jumps to the last used cell. Understanding this grid structure and interface is the essential starting point for everything else in Excel. The Excel Spreadsheet Fundamentals webinar from Aurora Training Advantage builds this core foundation for new users.

Entering data in Excel is straightforward: click a cell and start typing. Press Enter to confirm and move down, Tab to confirm and move right, or Escape to cancel. Double-clicking a cell (or pressing F2) enters edit mode, letting you modify existing content rather than replacing it. The Delete key clears a cell's contents while preserving formatting; the Backspace key removes the last character during editing. To clear formatting along with content, right-click and choose Clear Contents or use Home > Clear > Clear All. Typing numbers, text, and dates is handled automatically—Excel recognizes dates in common formats and aligns numbers right and text left by default. To enter a number as text (such as a leading-zero code like 00123), type an apostrophe first. Selecting a range and pressing Delete clears all selected cells at once. Undo (Ctrl+Z) reverses the last action, and Ctrl+Y redoes it. These fundamentals are covered in Aurora Training Advantage's Excel Spreadsheet Fundamentals webinar as the foundation for working confidently with Excel data.

Cell formatting in Excel controls how data looks without changing its underlying value. The Home tab provides the most-used formatting tools: font type, size, bold, italic, and underline; text color and cell fill (background) color; horizontal and vertical alignment; and number formats. Number formats change how values display—currency, percentages, dates, or custom formats—while the actual stored number remains unchanged. The Format Cells dialog (Ctrl+1) provides comprehensive formatting options across Number, Alignment, Font, Border, Fill, and Protection tabs. Merging cells (Home > Merge & Center) combines adjacent cells into one—commonly used for headers, though it can interfere with sorting and formulas. Wrap Text (Home > Wrap Text) displays long text on multiple lines within a cell rather than overflowing into adjacent cells. Borders add visual structure to tables. Formatting should enhance readability, not overwhelm data. Aurora Training Advantage's Excel Spreadsheet Fundamentals webinar teaches these formatting essentials as part of building professional, easy-to-read spreadsheets.

Inserting and deleting rows and columns are fundamental worksheet management skills in Excel. To insert a row, right-click a row number (the number on the left edge) and choose Insert—a new blank row appears above the selected row. To insert a column, right-click a column letter and choose Insert—a new column appears to the left. For multiple insertions, select the same number of existing rows or columns before right-clicking, and Excel inserts that many at once. Deleting follows the same pattern: right-click a row number or column letter and choose Delete. The Home > Insert and Home > Delete buttons on the Ribbon perform the same actions. Keyboard shortcuts: Ctrl+Shift+Plus inserts, Ctrl+Minus deletes. Note the difference between Delete (removes the entire row or column and shifts data up or left) and Clear Contents (empties the cells but leaves the row or column in place). Inserting rows can break fixed formulas that reference specific row numbers, so understanding relative references is important. Aurora Training Advantage's Excel Spreadsheet Fundamentals webinar covers these structural editing skills for building and maintaining organized spreadsheets.

Saving your Excel work correctly ensures data is preserved and accessible. Ctrl+S saves the current workbook; the first save prompts you to choose a location and filename. Excel's default format is .xlsx (Excel Workbook), which is the standard for most purposes. If your workbook contains macros, save as .xlsm (Excel Macro-Enabled Workbook)—Excel warns you if you try to save a macro file as .xlsx. For sharing with people who use older versions of Excel or non-Microsoft software, .csv (Comma-Separated Values) exports a single sheet's data as plain text, losing all formatting and formulas. PDF export (File > Export > Create PDF/XPS) produces a non-editable, print-ready version ideal for distribution. AutoSave (available in Microsoft 365 with OneDrive or SharePoint) saves changes automatically in the background. Save As (F12) creates a copy under a new name or location—useful for version control. Organizing workbooks in clearly named folders with date-stamped filenames prevents version confusion.
