is it HTML? cant view it via HTML viewer
It's a format proprietary to Alteryx called Composer with a file extension of .PCXML. In the past I've described it as "HTML content wrapped in XML for use by Alteryx", but that's not exactly accurate.
Is there something we can help you with?
Do we have whitebook on this language?
can we edit the layout by change something in the coding like formatting html page via any tool if possible.
