Customizing Excel Think of Excel Options dialog box as the control center Excel Options dialog box contains a variety of settings that control how Excel behaves You might want to personalize Excel to suit your needs. For example, you may develop most of your spreadsheets for a quarter budget with a summary sheet. You, therefore, need 5 sheets for most of your workbooks. One sheet for each of the 4 quarters and one for the summary sheet. This section of the chapter deals with customizing and personalizing Excel. The Excel Options dialog box permits you to change a variety of settings contained in the options category. These include: General, Formulas, Proofing, Save, Language, Advanced, Customize Ribbon, Quick Access Toolbar, Add-Ins (previously used), and Trust Center. Table 10.1 in your textbook describes each of these categories and some options contained in each. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.

Collaboration Collaboration occurs when multiple people work together to achieve a common goal by using technology to edit the contents of a file Collaboration tools include: Share , Compare and Merge Comments Track Changes We just finished with customizing and personalizing the workbook and now move to the concept of collaboration. Since team members work together to plan, develop spreadsheets, conduct quantitative research, enter data, and analyze the results, the ability to use the technology tools that enable collaboration is critical in today’s work world. Very few projects are worked on in isolation but are team efforts. In this section, you will learn how to share workbooks with others, compare and merge workbooks, insert and edit comments, and track changes. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.

Share and Merge Workbooks
Shared workbook is a file that enables multiple users to make changes at the same time Owner is the person who created the workbook and designates it as shared Owner controls user access and resolves conflicts A Shared workbook is one way to collaborate on a workbook . A shared workbook is designated as shareable and is stored on a network making it accessible to the project team. One advantage of shared workbooks is that you can see changes made by other users. The person who creates the workbook and designates it as a shared workbook is the owner. The owner controls user access and resolves any conflicting changes made. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.

Network Issues Network Permission determines who has rights to open and modify files Owner: full rights Read-Only: can not save changes back to network drive Non-Shareable: only one person can work on the workbook at the same time Second person receives File in Use notice When several people on a network share a workbook and make changes to it, the last person to make changes decides which changes to accept. This can be a problem if the least knowledgeable person is the last one to make changes. Other issues arise when storing and using files on a network. Furthermore, workbooks that have not been designated as shareable may still be able to be modified by various users. Network Permissions: Some users may have Read-Only permissions while others may have Owner permissions. Owners can open, save, delete, and modify files. Non-Shareable Workbook: A workbook may be stored on a network that you can access, but the workbook might not be designated as a shared workbook. This means only one person can work on it at a time. The second person who goes to open it, receives the File in Use notice. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.

Compare and Merge To use this feature: Each workbook must have a unique name (workbookname-lastnameuser) All workbooks must be stored on the same drive and in the same folder as the original shared workbook When you share a workbook with others, you might want to see what each person changed in the workbook instead of allowing immediate changes to the original workbook. To do this, you use the Compare and Merge Workbooks command. This combines the shared workbooks into one workbook so that you can compare the changes and decide which ones to keep. This command works only with copies of a shared workbook; it does not work on workbooks that have not been designated as shared. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.

Workbook Information Check for issues using document inspector, accessibility checker, and compatibility checker Protect the workbook by marking it as final and encrypting it, adding a digital signature, and a signature line We now move from collaboration tools to learning about workbook information. The focus of this section is preparing the workbook for sharing and protecting the workbook. You should remove your “fingerprints” from the file by removing any properties or identifying attributes that indicate your work on the workbook. This is especially important when distributing workbooks to others inside and outside your organization. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.

Protect Workbook Protection features include: Mark workbook as final Encrypt workbook with a password Add digital signature Add signature line You protect a workbook to ensure the integrity of its contents. Workbook protection includes marking the workbook as final, encrypting a workbook with a password, inserting a digital signature, and/or adding a signature line. The type of protection you add depends on the level of security you need to place on the workbook contents. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.
41
Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.
Mark Workbook as Final The Mark as Final command communicates that it is a final version and makes the file read-only. Figure shows the Mark as Final Verification box. It is asking for confirmation that this document is indeed final. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.
42
Encrypt a Workbook with Password
You can protect a workbook by restricting its access to authorized people only. This requires a password. Note that you cannot encrypt a file with a password if you have already marked it as final. You should also make a note of passwords you use for saving workbooks. If you forget a password, you will not be able to open the file. Note the caution statement of Figure Copyright © 2011 Pearson Education, Inc. Publishing as Prentice Hall.
43
Digital Signature and Line
A digital signature — an electronic notation in a document to authenticate the contents A signature line — enables a person to type or insert a visible digital signature to authenticate the workbook A digital signature is an electronic, encrypted notation that stamps a document to authenticate the contents, confirms that a particular person authorized it, and marks the workbook as final. Use a digital signature to ensure that a workbook is authentic and that the content has not been changed since the signature was added. You obtain the digital signature from a certified authority who can verify your signature. Instead of creating an invisible digital signature, you may want to include a signature line. A signature line is similar to a signature line in a printed document, such as a contract or legal document. In Microsoft Office 2010, an author can create a signature line to request someone type a signature, select an image containing a signature, or write a signature using a Tablet PC.

Workbook Distribution
Save a workbook in different formats .xls, .ods, .pdf, .csv to name a few Send a workbook to others the Web through SkyDrive Sharepoint site Excel provides means for you to change the file type and create different types of files from your Excel 2010 workbooks. Excel provides a variety of distribution methods so that you can provide others with easy access to your workbooks, whether that is as an attachment or uploaded to a server. Some of the most common formats are: .xls for saving as Office 2003 and lower files. .ods for saving as OpenDocument spreadsheets (open source suite). .pdf for portable document format which is a universal file format that preserves original format. .csv for comma delimited for importing into databases. Excel provides multiple methods to share your workbook with other people such as an attachment, on the Web through a central storage location like SkyDrive, or on a SharePoint site which is a central location for storing and accessing files.
