F. Long Answer Questions (Detailed)
Question 1. How do you create a hyperlink in LibreOffice Calc and what can you link to?
Answer:
To create a hyperlink in LibreOffice Calc, follow these steps:
  1. Select the cell where you want to insert the hyperlink.
  2. Go to the Insert → Hyperlink option from the menu bar.
  3. A dialog box will appear. Here, you can select the type of hyperlink.
  4. Web hyperlink: Allows you to link to a website using a URL (e.g., https://www.openoffice.org).
  5. Email hyperlink: Opens the default email client with a pre-filled address (e.g., mailto:abc@gmail.com).
  6. Document hyperlink: Creates a link to another document, sheet, or even a specific cell in the same or another spreadsheet.
  7. New Document hyperlink: Creates and links a new file.
  8. Enter the target address, text to display, and description if needed.
  9. Click Apply and then Close.
Hyperlinks in Calc are useful because they save time, improve navigation, and connect spreadsheets with external resources. For example, a company’s sales spreadsheet can include hyperlinks to product reports, websites, and customer records.


Question 2. Discuss further setting options in hyperlink.
Answer:
When inserting a hyperlink, Calc provides several additional settings that improve flexibility:
Target Frame: You can select where the hyperlink will open. For example, in the same window, a new window, or a named frame. This is especially useful in web-based reports.
Text Representation: You can define what text will be shown in the cell (instead of the full hyperlink address). This makes spreadsheets cleaner.
Tooltip: You can enter an additional description or note. When the user hovers the mouse over the hyperlink, this tooltip will be displayed.
Formatting: Hyperlink text can be styled (color, underline, bold). By default, hyperlinks appear blue and underlined.
Security Settings: In some cases, Calc may prompt you before opening external links, protecting users from accidental access to harmful files.
These advanced settings help in making hyperlinks not only functional but also user-friendly. For example, in financial records, instead of showing a long web link, you can simply display “Bank Statement” as the clickable text.
Question 3. How do you create a reference to another cell or sheet in Calc and why is it useful?
Answer:
Creating references is an important feature in Calc because it allows dynamic updates.
Reference within the same sheet: Simply type =A1 in another cell, and it will copy the value of cell A1.
Reference in another sheet: Use the format =Sheet2.A1. This will bring the value from Sheet2 cell A1 into your current sheet.
Reference from another file: Use a full path, for example:
Copy code

='file:///C:/Users/Documents/Report.ods'#$Sheet1.A1
Usefulness of References:
They eliminate duplication because the data is fetched from one source instead of copying it multiple times.
They ensure automatic updates. If the original cell changes, the referenced cell updates instantly.
They are widely used in financial reports, project planning, and data analysis. For example, a summary sheet can pull monthly totals from multiple sheets without retyping data.
Thus, references in Calc save time, reduce errors, and keep data consistent across spreadsheets.
Question 4. What is a registered data source in LibreOffice Calc and how do you link to it?
Answer:
A registered data source in LibreOffice is a database (such as MySQL, PostgreSQL, MS Access, or even a spreadsheet) that has been connected to LibreOffice so that it can be used across applications like Writer, Calc, or Base.
Steps to Register a Database:
  1. Go to Tools → Options → LibreOffice Base → Databases.
  2. Click New, then browse and select the database file or connection.
  3. Assign a name to the data source (this will be used later in Calc).
  4. Save and exit.
Linking in Calc:
Open Calc and press F4 to display the Data Source panel.
Select the registered database name.
Drag the required table or column into the spreadsheet.
The data will now appear in Calc, and you can update it dynamically.
Usefulness:
It allows importing live data from large databases.
Businesses can link customer data, sales figures, or inventory directly into Calc.
Updating the database will automatically update the Calc sheet, ensuring accuracy.
In short, registered data sources make Calc a powerful tool for handling professional databases and integrating them into everyday spreadsheets.
Question 5. Discuss the hyperlink and its categories.
Answer:
A hyperlink is a clickable object in Calc (usually text or image) that directs you to another location when clicked. Hyperlinks are powerful tools because they connect spreadsheets with other files, web pages, or even specific cells.
Categories of Hyperlinks in Calc:
Internet Hyperlink: Links to websites using a URL (e.g., https://www.wikipedia.org). Useful for referencing online resources.
Email Hyperlink: Opens the default email application and creates a new mail with a pre-set recipient (e.g., mailto:info@example.com).
Document Hyperlink: Links to a file on your computer or to another cell/sheet within Calc. For example, linking from Sheet1 total sales cell to Sheet2’s sales breakdown.
New Document Hyperlink: Creates a new file and links to it immediately. Helpful when working on reports that need new supporting documents.
Advantages of Hyperlinks:
  • Improve navigation inside large spreadsheets.
  • Connect data with external resources.
  • Reduce effort by directly linking to important files or references.
  • Make spreadsheets more interactive and user-friendly.
For example, in a project budget sheet, each expense item could be hyperlinked to the vendor’s invoice stored as a document. This ensures transparency and quick access.
