Excel I have a very large excel document (almost 90000 rows) and i need to autofill within this document. is there a faster way as i cannot imagine using the drag fill throughout

Have you tried the function within Data -> Text to columns?

right-click the sheet you want to copy, select "copy to", then either select the position within the current document, select annother document (needs to be open in the same excel instance) or select "new document". check the box "copy" to copy, leave unchecked to move.

Creating a table in Microsoft Excel 2007 allows you to work with that data independently of the rest of the worksheet. First you must define your table, though, which you can do either from scratch or from data already in the worksheet. The process is a simple one. Read on to learn how to define a table in Excel 2007

Start off by doing one of the following: Select the range of cells that you want to make into a table within your worksheet then proceed to Step 2 OR Start immediately with Step 2.

Click on the "Insert" tab at the top of the document.

Find the "Tables" group, then click on "Table." The "Create Table" dialog box will appear.

Type in a range for your table if you did not select a range in Step 1. If you did already select a range then that range will automatically appear in the dialog box.

Check the "My Table Has Headers" box if the data set you selected already contains the headers you want to use. If you don't check this box, the table will display default header names, which you can then go in and change.

Hit the "OK" button at the bottom of the Create Table dialog box to create your table.

The problem occurs, only when the CSV file was edited and saved by MS Excel. The solution: use only Notepad, Excel never!

More information is required so I will only assume you are using Excel as a database. Excel is a spread sheet program used by accountants or for mathematical formulas and ledgers. Access is the Database program, however, Excel has functions which is faster to sort and work with address, phone number, zip codes. I will confess, I use Excel as Database because it is quick and easy. I do not know what version of Excel you are using so I will describe it from Office 2007. From Excel make sure you have headers above each column i.e. First Name in Cell A1 Last Name in Cell B1 Address in Cell C1 ect.

Make sure your data is correct and case sensitive as you would like it. If you want zip+4 select the Colum and right click to format the cells using special and select Zip or Zip+4.
It is easiest to use Microsoft Word for the next step rather than format the cells, add page breaks, and customize the print size.
Save your document as an Excel document where you can find it to import it into Word.
Open word and select Mailings then Start Mail Merge and Step by Step Mail Merge.
Select Envelope and next. Select envelope options to change envelope size, font and print options.
Click on Next Select recipients.
Click on browse under select an existing list.
Select the Excel file with your address information.
From the Select Table check the First row of data contains column headers.
Click on the OK buton.
Arrange your envelope then Preview it and your good to go.
If you have an older version of word selects Tools and click on Mail Merge.
Select Get Data.
Pull down Excel for document type.
Select entire Spread Sheet.
Layout your document and complete the merge.
On old versions of word it may not recognize the Excel file. If this happens open the Excel file and save it as a Database File (.dbf) and it should work.
I hope this helps since I did not have enough information from your question.

go to Insert > File >select file and insert.
you have to select all documents when you when insert box opens.

Have you tryed this?
