Convert, merge and generate DOCX, PDF and XML files automatically in an Appian process

Key Features & Functionality

  • PDF from single DOCX with Fonts
    • Convert multiple DOCX files into a single PDF. Please note that the translation from DOCX to PDF is not always 1:1. The template may need to be tweaked or simplified to achieve the desired results.
  • PDF from DOCX without Fonts
    • Convert multiple DOCX files into a single PDF. Please note that the translation from DOCX to PDF is not always 1:1. The template may need to be tweaked or simplified to achieve the desired results. This will not support fonts.
  • PDF from XSL-FO Transformation
    • Uses XSLT to convert an XML to XSL-FO which is then converted to PDF
  • PDF from HTML
    • Converts an HTML document into a single page PDF.
  • PDF from HTML Transformation
    • Uses XSLT to convert an XML to HTML which is then converted to PDF
  • Text Doc from XSLT
    • Uses XSLT to convert an XML to a plain text document (such as HTML, another XML doc, etc).
  • DOCX from XHTML With Styling
    • Converts a valid XHTML file into a DOCX, allowing you to provide your own template file for style reference. Useful for creating dynamic documents that are editable
  • DOCX Merge
    • Merges one or more DOCX files together. If a header or footer exists in any document, they will be removed during the merge process.
    • A configurable separator can be specified: none, line break or page break

Function: xsltransform - Transform source XML using XSL Transform

  • We are using this plug in and the PDF from HTML smart service and started receiving errors yesterday and today.  It has been working for at least a month and just started failing in all environments today.  Here is a section of our tomcar-stdOut.log. It does appear that  it is a timeout issue, there are 2 in about 100 that do get converted.
