Use XML Maps

If all of the XSLT in the preceding sections intimidated you, relax a bit. Excel also provides graphical tools for importing XML into workbooks through XML maps. XML maps are the way Excel represents XML schemas within a workbook. Excel can generate these maps from the structure of an imported XML file, or Excel can load an XML schema as an XML map.

Excel uses XML maps as a way to bind data from an XML file to cells and list columns on a worksheet. You create this binding by selecting items from an XML map displayed in the XML Source task pane and dragging them to locations on a worksheet.

Note

You don’t have to know XSLT to read or write XML from Excel. XML maps let you work with XML at a higher level and ignore some of the complexities.

How it works

1. Open the sample file SimpleOrder.xml in Excel using the regular File Open menu. Excel displays the Open XML dialog box (Figure 3-5).

2. Select the Use the XML source task pane option and click OK. Excel creates a new, blank workbook and informs you that the file did not contain a schema (Figure 3-6), so Excel will infer one from the XML.
