Outlook folders Importing a contacts or tasks folder from Outlook is an effective way to add this information to a database. Import options include Structure Only, Structure And Data, and Append Data To Existing Table(s). XML files Access uses the structure of the XML file to determine table names and fields. To import HTML document data, the file must reside on your computer or on your network. Both types are suitable for import into Access so that you can perform more extensive data analysis. Although this data is usually text, some HTML data comes either as a table (a rectangular array of rows and columns) or as preformatted text (text that has been structured with a predefined spacing used to organize data into columns with fixed widths). HTML documents Data is often available in documents created using HTML (Hypertext Markup Language), which is the language used to build web pages. Three of the other formats you can import are as follows: The wizard also prompts you to set up a primary key for the table. You can name fields, specify a data type, indicate whether the field should be indexed, and skip a specific field. The later pages of the Import Text Wizard are similar to those you work with in the Import Spreadsheet Wizard. For delimited text files, you must specify which character is used as the delimiter for fixed-width files, you indicate where column breaks should occur. In the wizard, you first need to specify whether a character separates the fields of data in the text file (a delimited text file) or whether the data is arranged in fixed-width columns. When you import data from a text file, you work with the Import Text Wizard. You can import data from a text file that uses the. A link is maintained with the original data, so if that data changes, the changes are reflected in the Access version of the data.įor information about running saved import and export operations, see “Objective 1.3: Print and export data.” Access adds the source data to the new table. Link to the data source by creating a linked table. No link is maintained with the original data. If the table does not exist, Access creates it. Access adds the source data to the existing table. No link is maintained with the original data.Īppend a copy of the records to an existing table. Access either creates a new table to hold the data or replaces any data in an existing table. Import the source data into a new table in the current database. Depending on the type of data source you are using, Access gives you one or more of the following choices for importing the data: If the data you want to work with resides in an external data source-usually a local file, a remote file (on a network or on the Internet), or data on a server-you need to import it into Access. For more information, see “Download the practice files” in this book’s Introduction. To complete the practice tasks in this chapter, you need the practice files contained in the MOSAccessExpert2019\Objective2 practice file folder. This chapter guides you in studying methods for importing data into tables, managing tables and records in tables, and creating and modifying fields. You can either create a copy of the external data or you can set up a link between the original data and your Access table, which means that changes made to the external data are also propagated to the Access version of the data. In that case, it’s easier and faster to import the data from its current format to an Access table. However, for many database applications the data already resides in some other format, such as an Excel spreadsheet, an HTML document, a text or XML file, or another database. You can also create your own tables as needed. When you create a database, Access automatically creates a new table that you can use to enter data by hand. Specifically, the following objectives are associated with this set of skills: The skills tested in this section of the Microsoft Office Specialist Expert exam for Microsoft Access 365 and Microsoft Access 2019 relate to creating and managing tables.
