Proof of concept iXBRL converter to XBRL
In the examples provided, each case has an iXBRL file (in both versions, with and without iXBRL viewer) and the corresponding XBRL instance document. See for instance the report Ferrovial2016
The proof of concept iXBRL converter to XBRL is a simple Excel spreadsheet with a small VBA program asking for an iXBRL file and generating the corresponding XBRL instance document, while showing the content in a spreadsheet. The hence generated XBRL file would be then compared with the example XBRL.
The converter is operational but still incomplete. Comments welcomed to email@example.com !
