Form authoring in formhub is based on the XLSForm standard. While there is an initial
learning curve, we’ve found that XLS provides a great interface for authoring forms — whether it’s
simple 5 question questionnaire or a complex survey with hundreds of questions. XLS also makes
sharing and collaborating on forms easy. Whether you need help authoring your first form or want
to pick up advanced tips, please check out our
XLForm Syntax page and
our gallery of sample forms on
formhub University.
