What is an ODKBUILD file?
An ODKBUILD file is a form created using ODK Build, a form-designing application included in the Open Data Kit. It contains JSON-formatted text used to display a form's fields in ODK Build. ODKBUILD files are created by selecting Save Form to File... while editing a form in ODK Build.
Open Data Kit is a free, open-source toolkit that allows developers to create forms and gather data using Android devices. Typically, developers create ODK forms using either XLSForm or ODK Build. Forms created using ODK Build are saved as ODKBUILD files.
When viewed in ODK Build, an ODKBUILD file looks like a series of blocks describing form fields. When you select a block, the corresponding field's properties appear in ODK Build's Properties sidebar.
You can add new fields to an ODK Build form by selecting the appropriate field type from the Add new menu that appears at the bottom of ODK Build. You can delete a field by selecting the X that appears in the upper right-hand corner of that field. You can also export the form an ODKBUILD file describes as an .XML or .XLSX file.
How to open an ODKBUILD file
You can open an ODKBUILD file in ODK Build (cross-platform). To do so, select File → Load Form from File... from ODK Build's menu bar. Then, navigate to and open your ODKBUILD file.
The title, form fields, and field properties an ODKBUILD file contains are defined by JSON text. If you want to view your ODKBUILD file as JSON text, you can open the file in Microsoft Notepad (Windows), Apple TextEdit (Mac), or any other text or source code editor.
