ESEF explained

ESEF compliance by Workiva

W for ESEF is a cloud solution that is built on the same secure infrastructure as all Workiva products. The solution enables customers across Europe to fulfil their ESEF compliance and filing requirements with integrated iXBRL® tagging, review and validation capabilities, as well as a simple, one-click XHTML with iXBRL output. 

Meet your ESEF requirements with Workiva, a proven global leader in XBRL® and iXBRL, and take advantage of the flexibility to easily upgrade to our connected reporting and compliance platform.

Meet the ESEF requirements



There is no installation required, and your data does not leave our secure servers.

W for ESEF utilises numerous measures to provide rigorous safeguards and the highest level of security. Plus, you can manage access and control by team or contributor.


You have access to intuitive XBRL tagging, integrated validations and error resolution, review tools and even the 2022 text block tagging requirements. And, it’s all in one place.



No pencils down

Tagging is done within the system, so your report is accessible at all times in case you need to make additional updates.

Make last-minute edits, and see the changes flow throughout your report and the XHTML without the need for reconversion or a pencils down period.

Collaboration with control

All of your teams can work on your report at the same time with an audit trail to track changes. 

You have full version control of your document, so you can allow or restrict access throughout the document on a section by section level.


Your output will include your entire annual report content while being fully compliant with the ESEF requirements. This means your XHTML with iXBRL and your PDF will all be exported from the same document with identical content.

Unlimited users

You can have as many users as you like without any additional cost.

This includes your internal and external auditors, board and executive team who will need to review and sign off on the XBRL.
