Hi,

Have you tried online? If the conversion doesn't work online, try to convert online. The online converter also allows you to preview the form on Enketo form viewer.

Hope this helps!

Thanks

Check out [http://xlsform.org/en/#multiple-language-support](http://xlsform.org/en/#multiple-language-support) and [https://docs.opendatakit.org/form-language/](https://docs.opendatakit.org/form-language/) for more details about using multiple languages in a form.

If you are defining multiple languages in your form you should follow the format  
`label::language1 (code)`  
for example  
`label::english (en)`

If you only have 1 language in your form, you should be able to safely ignore the warning.
