To open data preview, simply click the dark blue bar at the bottom to open it. Below you'll see a screen with the form data shown. This is useful for complex figuring out calculations in on hidden values , obviating the need for debug labelswithout submitting the form to the server.

Next Steps
In addition to the usual feedback on bugs and UI suggestions, we're interested in feedback from the field team and other power users about what enhancements or extensions would be useful for the next iteration of this feature. This is a feature that could evolve in many ways and we want to be directed about how we invest in this feature. Possible next steps are:
- Ability to inspect external instances (IE casedb, fixtures, ledgerdb, etc.)
- Click on XML, get XPath
- Perform calculations on XPaths
...
The debugger is also available in live preview. You can access it when you are in a form. Look for a data table icon in the bottom right.

Advanced Usage
In most scenarios, viewing just the form data is enough to get insight on your application. However, Data Preview also offers the ability to query your data as well as view the raw xml of the form.
Evaluate XPath
The Evaluate XPath tab allows users to evaluate arbitrary XPath clauses on their data. This is useful to test different conditions or expressions with the form in the current state. Note: you need to use /data/... syntax rather than the #form/... syntax as you would in Formbuilder!
...
Form XML
In other cases, you may desire to see the actual form XML that is being generated by the form. You can do this by selecting the Form XML tab.
