Suppose that a Microsoft Excel file contains one row of data from Big Class.jmp. The file is saved as the valid XML document BigclassExcel.xml, shown here and also saved in the JMP Samples/Import Data folder.

The following script reads BigclassExcel.xml and creates a JMP data table with the information in it. This script, named ParseXML.jsl, is in the JMP Samples/Scripts folder.
file contents = Load Text File( "$SAMPLE_IMPORT_DATA/BigclassExcel.xml" );
Parse XML( file contents,
OnElement(
"urn:schemas-microsoft-com:office:spreadsheet^Worksheet",
StartTag(
sheetname = XML Attr(
"urn:schemas-microsoft-com:office:spreadsheet^Name",
"Untitled"
);
dt = New Table( sheetname );
row = 1;
col = 1;
)
),
OnElement(
"urn:schemas-microsoft-com:office:spreadsheet^Row",
StartTag(
If( row > 1, // assume first row has column names
dt << Add Rows( 1 )
)
),
EndTag(

OnElement(
"urn:schemas-microsoft-com:office:spreadsheet^Data",
