Is there any demo data available for current versions of ERPNext?
It is important because many of my clients want to see the Working demo of ERPNext to get trust on it.
It is highly appreciable if you provide demo data in a separate demo site.
or Demo Data can be in the form of sheets which can be import through Data Import/Export process.
We made the decision to create this demo data via script, so that we can tell the stories that we want to be able to showcase regard Frappe/ ERPNext/ custom-developed features. It represents hundreds of hours of work. What you’re asking for is non-trivial.
That said, if you just need data, you could try translating the Northwind ERP database - its models are inferior to Frappe/ERPNext and would need to be changed to reflect it.
