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.
boolean showHeaders - If true (1), the spreadsheet will include a header row.
Object datasets - A sequence of datasets, one for each sheet in the resulting workbook.
String - An Excel-compatible XML-based workbook, with one worksheet per dataset.
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"
