is a certain limit of items that can be exported. It could vary depending on
the browser, it's version, the operating system, so there is no specific number
to be stated. The reason is that modern browsers do not provide support for
streams. This means that we have to keep all data in memory until the file is
generated on the client side. It's a limitation that we won't be able to
overcome in the foreseeable feature. If exporting all of the items is required,
we do not recommend using the built in PDF and Excel export functionality.

Export with large number of data results in a failure, both Excel and PDF.
