Validate data against schema for import and export Specifies whether Excel validates data against the XML map when importing data. Overwrite existing data with new data Specifies whether data is overwritten when you import data. Click this option when you want to replace the current data with new data, for example, when up-to-date data is contained in the new XML data file. Append new data to existing XML tables Specifies whether the contents of the data source are appended to the existing data on the worksheet.
Click this option, for example, when you are consolidating data from several similar XML data files into an XML table, or you do not want to overwrite the contents of a cell that contains a function.
When you import XML data, you may want to overwrite some mapped cells but not others. For example, some mapped cells may contain formulas and you don't want to overwrite the formula when you import an XML file.
There are two approaches that you can take:. Unmap the elements that you don't want overwritten, before you import the XML data.
After you import the XML data, you can remap the XML element to the cells containing the formulas, so that you can export the results of the formulas to the XML data file. In this "Import" XML map, don't map elements to the cells that contain formulas or other data that you don't want overwritten. Use another XML map for exporting the data. If you open a workbook that was created in Excel , you can still view the data, but you cannot edit or refresh the source data.
The inferred schema is stored with the workbook, and the inferred schema allows you to work with XML data if an XML schema file isn't associated with the workbook.
Select the Preview Data in Task Pane option from the Options button to display the first row of data as sample data in the element list, if you imported XML data associated with the XML map in the current session of Excel. You cannot export the Excel inferred schema as a separate XML schema data file. Although there are XML schema editors and other methods for creating an XML schema file, you may not have convenient access to them or know how to use them. You export XML data by exporting the contents of mapped cells on the worksheet.
When you export data, Excel applies the following rules to determine what data to save and how to save it:. Empty items are not created when blank cells exist for an optional element, but empty items are created when blank cells exist for a required element.
Excel overwrites existing namespace prefixes. The default namespace is assigned a prefix of ns0. Excel has a defined XML schema that defines the contents of an Excel workbook, including XML tags that store all workbook information, such as data and properties, and define the overall structure of the workbook. For example, developers may want to create a custom application to search for data in multiple workbooks that are saved in the this format and create a reporting system based on the data found.

Method 1. Open Microsoft Excel. Click Open. This opens the file browser. Double-click the XML file. Depending on the format of the file, you may have to take additional steps to open this file: If you see a dialog box called Import XML, the file references at least one XSLT style sheet. Select Open the file without applying a style sheet to select the standard format, or Open the file with the style sheet applied to format the data in accordance with the style sheet.
The schema definition of a mapped element is contained within a sequence with the following attributes:. The sequence has more than one direct child element defined, or has another compositor as a direct child. Nonrepeating sibling elements with the same repeating parent element are mapped to different XML tables. Multiple repeating elements are mapped to the same XML table, and the repetition isn't defined by an ancestor element.
List of lists One list of items has a second list of items. Denormalized data An XML table has an element that has been defined in the schema to occur once the maxoccurs attribute is set to 1. When you add such an element to an XML table, Excel fills the table column with multiple instances of the element.
In the XML Source task pane, select the elements you want to map to your worksheet. You can always ask an expert in the Excel Tech Community or get support in the Answers community.
Overview of XML in Excel. In the File name box, type a name for the XML data file. Click Export. When you export XML data, you may get messages like the ones below. The XML Map can be exported but some required elements aren't mapped. The element is a recursive structure. The XML table contains mixed content. This relationship may not be preserved for the following reasons: The schema definition of a mapped element is contained within a sequence with the following attributes: The maxoccurs attribute isn't equal to 1.
Child elements from different parents are mapped to the same XML table. Excel can't save the workbook because it doesn't have any mapped ranges. Excel can't save your workbook in the XML Data file unless you create one or more mapped ranges. To select nonadjacent elements, click one element, hold down CTRL, and then click each element.
