General Discussion

Hi guys, Have a good days.

Currently I’m trying to save the table data to pdf format. I’m able to saved it in pdf file but the pdf file cant open.
Below are my sample code to export table data to pdf format

fileName1 = "Audit_Log.pdf"
data1 = system.db.runNamedQuery("Login_Logout")
excelbytes1 = system.dataset.dataSetToHTML(1, data1, "Audit Log")
#excelbytes1 = system.file.readFileAsBytes(1, data1, "Audit Log")
system.perspective.download(fileName1, excelbytes1)

Thanks in advance.

You are converting a dataset to HTML, but trying to deliver that as a PDF. There’s no magic that will convert HTML to PDF for you.

Thanks Mr pturmel. I just notice that sorry for my mistake. May I know what is the best way to do this ?

The supported way to get a PDF is to define a report with a table containing your dataset, then execute your report to get the bytes to download.

It will not solve the problem in this post directly, but I'd like to leave an honorable mention for a piece of genuine magic: pandoc, which converts to/from a dizzying array of formats (admittedly, with limited degrees of success):
