IMPORTING DATA
Importing is the process of inserting data from one application or file into another.
Excel lets us import a few different types of data!
5
IMPORT(ANT) DECISIONS
Decide ahead of time if you want to embed data or link to it.
Embedded data: Is not linked to the original source, and can be edited. A change in the data in one place does not affect the other.
Data as a connection: Linked to the original data, Excel can then be refreshed from the source and the data updated if any changes are made.
6
IMPORT A TEXT FILE
Text Files: (Notepad, anyone?)
– .txt file extension (SomeTitle.txt)– No formatting– No sound– No video– Lots of data!
7
WHERE DO THEY COME FROM?
“When a text editor loves a character…”
• Can be created in Notepad• Can be downloaded from an organization’s
website (things like accident statistics, cars sold, etc)
*The benefit is that you can import a text file into multiple different programs, without distorting the text.
8
DELIMITERS!
Delimiters are special characters that separate the data, so it doesn’t run together.
The most common delimiters:
Tabs: TAB (Tab delimited)
Commas: , (Comma Separated Value “CSV”)

IMPORTING FROM ACCESS
• Databases are usually less intuitive about manipulating data, or lack the ability to do so
• Maintaining a database connection (in this case Access) eliminates the need to copy/paste data into Excel
18
ACCESS IMPORT STEPS
1. Start Excel, open an existing workbook
2. Click the Data Ribbon -> Get External Data -> From Access
3. Select the Access Database File, click open
4. Choose the table or query to import (Tables are one rectangle, queries two)
5. Select how you want to view the data in your workbook, such as Table or PivotTable

OTHER DATA SOURCESSource Definition

XML
eXtensible Markup Language (XML) – is an industry standard for structuring data that enables data to be shared across applications, operating systems, and hardware.
21
WHY XML?
• It enables data to be sent/received between disparate and otherwise incompatible systems.
***Sidenote: XML describes the structure of data, not the appearance or formatting.
