Electronic SpreadSheet Advanced - Class X and IX
Mastering Advanced Electronic Spreadsheet Functions: A Professional's Guide (UNIT-2)
Unlock the full potential of your spreadsheet software with these powerful advanced features, designed for comprehensive data management, robust analysis, and seamless team collaboration. Every detail of the core content is retained for thorough understanding.
1. Data Management and What-If Analysis Tools
1. Data Consolidation (1)
Data Consolidation gathers data from separate worksheets (or workbooks) into a master worksheet, summarizing it into a single, easily updatable view. The data from the consolidation ranges and target range are saved when you save the worksheet, remaining available upon subsequent opening.
Access: Data menu → Consolidate option
2. SUBTOTAL Function (2)
The SUBTOTAL function, listed under the Mathematical category in the Function Wizard, totals or adds data arranged in an array (a group of cells with labels). The graphical interface allows selecting arrays and choosing a statistical function. For efficiency, you can choose up to three groups of arrays. The resulting subtotals and grand totals use the Result and Result2 cell styles.
Access: Data → Subtotals
3. Scenarios (3)
Scenarios are a tool to test “what-if” questions. Each scenario is named, editable, and formatable separately. A scenario is essentially a saved set of cell values for calculations. You can switch between these sets using the Navigator or a drop-down list. When you print, only the content of the currently active scenario is printed. Formulas relying on the changed values are updated when the scenario is opened.
Access: Tools > Scenarios
4. Goal Seek (4)
Using the Goal Seek option, you can discover what input values will produce a desired result. Only one argument can be altered in a single goal seek operation.
Access: Tools menu → Goal Seek option
5. Solver (5)
Solver is a more elaborate form of Goal Seek, dealing with equations that have multiple unknown variables. It is specifically designed to minimize or maximize a result based on a defined set of rules (constraints). These rules set whether an argument should be greater than, lesser than, or equal to a value. You can define a range of possible values by adding two rules (limiting conditions). Constraints can also require variables to be integers or binary values (0 or 1). Clicking 'Solve' adjusts the argument and results.
Access: Tools menu → Solver option
2. Sheet Organization, Referencing, and Linking
Sheet Operations and Linking (6-11)
6. Linking Cells Across Sources: Spreadsheet software allows you to link cells from various worksheets and various other spreadsheets to summarize data from several sources. This enables formulas that span different sources and perform calculations using a combination of local and linked information. Multiple sheets help keep information organized.
7. Default Sheets: When you open a new spreadsheet, by default, it has a sheet named Sheet1 which is managed using tabs at the bottom of the spreadsheet.
8. Inserting New Sheets:
- Select Insert > Sheet from the menu bar, or
- Right-click on the tab and select Insert Sheet, or
- Click in an empty space at the end of the line of sheet tabs.
9. Inserting Sheets from a Different Spreadsheet File: On the Insert Sheet dialog, you can also add a sheet from a different spreadsheet file. For a shortcut, choose Insert > Sheet from file from the menu bar. The Insert Sheet dialog opens with the From file option preselected, followed by the Insert dialog.
10. Linking Sheets from a Different Spreadsheet: You may select the Link option to insert the external sheet as a link instead of a copy. This includes “live” data from another spreadsheet. The links can be updated manually or automatically (based on settings in Tools > Options > OpenOffice.org Calc > General > Updating) when the file is opened.
11. Renaming Worksheets: There are three ways you can rename a worksheet:
- Double-click on one of the existing worksheet names.
- Right-click on an existing worksheet name, then choose Rename from the resulting Context menu.
- Select the worksheet tab and then select the Sheet option from the Format menu, then select the Rename option.
Referencing and Hyperlinks (12-17)
12. Create Or Change A Cell Reference: A cell reference refers to a cell or a range of cells on a worksheet and is used to find the values or data for formulas. In formulas, you can refer to:
- Data from one or more contiguous cells on the worksheet.
- Data contained in different areas of a worksheet.
- Data on other worksheets in the same workbook.
13. Referencing Other Sheets: There are two ways to reference cells in other sheets: by entering the formula directly using the keyboard or by using the mouse. The sheet name will be in single quotes if it contains a space, and the mandatory period (.) always falls outside any quotes.
14. Referencing Other Worksheets (Files): Calc can link different files together by adding one more parameter to indicate the file. The reference has three parts:
- Path and file name
- Sheet name
- Cell
The general format is: ='file:///Path &File Name'#$SheetName.CellName.
15. Working with Hyperlinks: Hyperlinks can be used in Calc to jump to a different location from within a spreadsheet. They can lead to other parts of the current file, to different files, or even to web sites.
16. Relative And Absolute Hyperlinks: Hyperlinks can be stored as either relative or absolute:
- An absolute link will stop working only if the target is moved.
- A relative link will stop working only if the start and target locations change relative to each other (e.g., moving the entire containing folder does not break it).
You can change how OOo saves hyperlinks in Tools > Options > Load/Save > General. Links are inserted/modified using the Hyperlink dialog (icon on the Standard toolbar or Insert > Hyperlink).
17. Linking To External Data: You can insert tables from HTML documents, and data located within named ranges from an OpenOffice.org Calc or Microsoft Excel spreadsheet. This is done in two ways: using the External Data dialog (Insert → Link to External Data) or using the Navigator.

3. Collaboration and Change Tracking
Sharing Documents (18-21)
18. Sharing Workbooks: In shared office settings, a message often appears: “The document [file name] is locked for editing by another user...” To allow multiple people working on a file at the same time (for collaboration or data entry), the spreadsheet software allows the user to share the workbook and place it in a network location where several users can access it simultaneously.
19. Activating Sharing: With the document open, choose Tools > Share Document to activate collaboration features. A dialog allows enabling or disabling sharing.
20. Disabled Features in Shared Mode: When opened, a message confirms the worksheet is in shared mode and that some features are not available. These known disabled features include:
- Edit > Changes, except for Merge Document
- Edit > Compare Document
- Edit > Sheet > Move/Copy & Delete
- Insert > Cells Shift Cells Down & Shift Cells Right
- Insert > Sheet from file
- Insert > Names
- Insert > Comment
- Insert > Picture > From File
- Insert > Movie and Sound
- Insert > Object
- Insert > Chart
- Insert > Floating Frame
- Format > Sheet > Rename, Tab Color
- Format > Merge Cells > Merge and Center, Merge Cells, Split Cells
- Format > Print Ranges
- Tools > Protect Document
- Data > Define Range
- Data > Sort
- Data > Subtotals
- Data > Validity
- Data > Multiple Operations
- Data > Consolidate
- Data > Group and Outline (all)
- Data > DataPilot
21. Saving in Shared Mode:
- If the worksheet was not modified and saved by another user, the worksheet is saved normally.
- If modified by another user:
- If changes do not conflict, the worksheet is saved, and cells modified by the other user are shown with a red border.
- If changes conflict, the Resolve Conflicts dialog is shown. You must decide which version to keep (yours or the other person’s) for each conflict.
- If another user is already saving and resolving conflicts, you see a message that the file is locked due to a merge-in in progress.
- Successful saving updates the worksheet to show the latest version of all saved changes.
Change Tracking and Review (22-28)
22. Tracking Changes: Calc can track what data was changed, when, who made the change, and in which cell. Activate via Edit > Changes > Record. A colored border with a dot appears around changed cells; deleted rows/columns are marked by a heavy colored bar.
23. Customizing Change Colors: The color indicating changes can be modified in Tools > Options > OpenOffice.org Calc > Changes.
24. Filtering Changes: You can control what changes you see when reviewing by selecting Edit > Changes > Show to adjust available filters.
25. Adding Comments: Calc automatically adds a comment describing the change (e.g., Cell B4 changed from ‘9’ to ‘4’). Reviewers and authors can add supplementary comments using Edit > Changes > Comments.
26. Accepting or Rejecting: As the original author, you can step through each change and decide how to proceed using Edit > Changes > Accept or Reject.
27. Merging Worksheets: To review multiple edited versions simultaneously, Calc provides the feature of merging worksheets via Edit > Changes > Merge Document.
28. Comparing Documents: If reviewers forget to record changes, Calc can find them by comparing the original worksheet and the edited one via Edit > Compare Document.
4. Automation with Macros
Macros (29)
29. Macro Definition: A macro is a saved sequence of commands or keystrokes stored for later use. The OpenOffice.org (OOo) macro language is highly flexible, allowing automation of both simple and complex tasks. Macros are especially useful to repeat a task the same way over and over again.
Access: Tools > Macros > Record Macro
