Code Examples
Code Snippet
#This snippet would prompt the user to save the data currently displayed in a Table component to a CSV file, and would open the file (in an external program, presumably Excel) after a successful save.
 
table = event.source.parent.getComponent("Table")
filePath = system.dataset.exportCSV("data.csv", 1, table.data)
if filePath != None:
	system.net.openURL("file:///"+filePath.replace('\\','/'))

 

To write silently to a file, you cannot use the dataset.export* functions. Instead, use the toCSV() function as below:

Code Snippet
### This script DOES NOT USE the system.dataset.exportCSV() function ###
 
# take data and silently write it in CSV format to a file
# this script would be on a button with a from a table in the same container 

# get data
data = event.source.parent.getComponent('Table').data
# convert to csv 
CSVdata = system.dataset.toCSV(data)
# write file
system.file.writeFile("C:\\temp\\data.csv", CSVdata)

    Is there a way to enter the File Path and bypass the user prompt?

    1. Yes, but to do that you would need to use the system.file.writeFile() function instead of exportCSV().
