XBRL Company Accounts Validator

Welcome to the XBRL / iXBRL Online Validation Service

This is a service that checks your instance document for conformance to the XBRL specification and to business validation rules (this validation may be performed for both inline XBRL and 'raw' XBRL documents).

The service will also provide, for inline XBRL documents, a generated image of the accounts (that will mirror the image generated by the Companies House live service).

Overview of how the Validator process works.

To use this service enter the location of the instance document taxonomy file and select 'Validate'

For inline XBRL documents, you may view the generated image by selecting 'Show image'.

The validation process may take a few minutes
