QlikView - Web File


Advertisements


QlikView can process files from the web, which are in the HTML format. It can extract data from HTML tables. The URL of the web file to be processed is given as an input and QlikView fetches both, the structure and content of the file. Then it analyzes the structure of the page extracting the relevant data from the HTML tables present in the page. We choose the Web files option from the Data from files section under the Data tab of script Editor.
