Mail merge and Letter preparation.

Aim: To prepare a letter using mail merge concept

MAIL MERGE

Mail merge is powerful feature in MS Word that helps you to create form letters, mailing labels, envelopes, or catalogues. With mail merge you can get rid of the usual practice of cutting and pasting labels in every copy of the letter.

The body of the letter is typed and saved in as a file named main document. The addresses are typed and stored in another file called data source. By doing a mail merge you are linking the main document with the data source. Another advantage of using mail merge is that the next time you need to send a letter to the same set of recipients, you can use the same data source file.

Getting Started with Mail Merge

Step 1: Click Start All Programs Microsoft Word.

Step 2: Click Tools Letters and MailingsMail Merge

Select document type Letters

Step 3: Next: Starting documentSelect ‘Use the current document’

Step 4: Next: Select recipients-select ‘Type a new list’

Step 5: Click Create link

6

Step 6: Type the list of addresses(at least 3) and click to close. (Close will automatically save –Give a name of the file).

Step 7: Next: Write your letter

MS EXCEL CASE STUDY

MS Excel is spreadsheet software used to create and manage data and also for analyzing the data for information. The usage of this software is similar to MS Word, and is simple menu-driven software.

Excel spreadsheet consists of a grid of rows and columns. The intersection of a row and a column is called a cell. The rows are numbered 1, 2, 3 ….and so on, and columns are labelled alphabetically A, B, C… and so on. Each spreadsheet contains 16384 rows and 256 columns that make 4,194,304 cells. Each cell can store a piece of text, number or formula in it.

Getting Stared with Excel:

Click Start All Programs Microsoft Excel to start.

12

Parts of an Excel Spreadsheet :Just like MS Word we have the Title bar, Menu Bar, Tool bar, Formatting Tool bar, Scroll bar etc. In addition to these, there are Formula bar and Cells to store and work with data.
