LibreOffice Calc Course – Basics: Lesson 1
Introduction and Spreadsheet Fundamentals
With this first lesson we enter the world of LibreOffice Calc, the powerful open source alternative to Excel. Starting from a blank sheet, we will turn the simple interface into an "automatic calculator”.
The learning path of this first lesson develops through the key concepts needed to move around confidently:
The Work Environment
The logic of the grid, where columns (letters) and rows (numbers) intersect to create cells (e.g. B2), independent entities ready to hold data and formulas.
Space Management
How to avoid display errors by correctly working with the gray headers and using quick column-fitting tricks.
Formatting and Aesthetics
Basic rules for using fonts, bold, colors, borders and alignments (horizontal and vertical) to make data readable and professional.
Appearance vs. Reality (The Formula Bar)
Distinguishing what appears on screen (e.g. the euro symbol) from the actual pure numeric content that calculations depend on.
Declaring Data Types
How to instruct the sheet (cell formatting for dates, numbers and decimals, currencies, etc.).
Introduction to Formulas and Automation
Using the = symbol as an activation key and referencing cells instead of fixed numbers, using recursive copying to extend formulas across hundreds of rows in an instant.
Decoding Errors
How to interpret signals such as ### or #VALUE! and quickly fix data-entry errors.
