This feature was removed from Ignition in version 8.0.7

This function has been replaced with system.dataset.toExcel.

This function is used in Python Scripting.


Formats the contents of one or more datasets as an excel spreadsheet, returning the results as a string. Each dataset specified will be added as a worksheet in the Excel workbook. This function uses an xml-format for Excel spreadsheets, not the native Excel file format.

Code Examples
Code Snippet
# This snippet would run a SQL query against a database, and turn the results into a string that is XML that Excel can open. It then writes the string to a file on the local hard drive.
results = system.db.runQuery("SELECT * FROM example1 LIMIT 100")
results = system.dataset.toDataSet(results)
spreadsheet = system.dataset.dataSetToExcel(1, [results])
filePath = "C:\\output\\results.xls"
system.file.writeFile(filePath, spreadsheet)
