Issue Details

  • I would like to view a sequence file, but I do not have access to a TestStand license. Is there any option to open a sequence without TestStand installation?
  • I want to save my sequence files in a readable format to track changes, implement source code control, print, or otherwise archive.


National Instruments makes it possible to read TestStand's sequences in a Sequence File Viewer, which is available for free download on NI Labs as a part of the NI
TestStand Toolkit for Large Application Development.

You can get the toolkit here: NI TestStand Toolkit for Large Application Development

As long as your sequence file is saved in the XML format, the Sequence File Viewer tool can be used to view your sequence files. 

To ensure that your sequence will be viewable by the Sequence File Viewer, check the following:
  • You are using TestStand 4.0 or later. The XML format for sequence files is not supported in versions earlier than TestStand 4.0, therefore sequences created in previous versions will not be viewable with the Sequence File Viewer
  • Your sequence file is saved in XML format. Follow these steps to change the file format to XML:
  1. Navigate to Edit»Sequence File Properties
  2. In the General tab, select XML (most readable, largest) in the File Format dropdown menu
  3. Save the sequence file

You also may want to set XML as the default file format for new sequence files.  This can be accomplished with the following steps:
  1. Navigate to Configure»Station Options
  2. In the File tab, click the File Format Options... button
  3. In the General tab, select XML (most readable, largest) in the File Format For New Files dropdown menu


Additional Information

You can also view XML sequences in any text editor, but the information is presented in a more user friendly manner in the Sequence File Viewer tool.
