23-01-2026 DNB publishes Excel submission file for MESREP taxonomy version 4.0.0 with new functionality

An alternative submission facility is available for institutions that cannot easily create an XBRL file. This is an Excel file that is made available by DNB in the Reporting Service, which is automatically converted to the required XBRL format after receipt by DNB, provided it has been filled out correctly. This Excel file for MESREP taxonomy version 4.0.0 has now also been published on the MESREP documentation page.

In the Excel file, several preprocessing steps have been included to minimise the risk of incorrect submissions. These steps include – as in previous versions – the insertion of formulas for roll ups in the overview form and the display of empty values in the dimensions, ensuring that the reporter is required to make the correct selection.

A new feature is that the ‘filing indicator’ on the Table of Content is automatically set to ‘positive’ as soon as an amount is entered on the relevant form.

In addition, the forms in reporting profile IFSB (for the smaller investment funds) now indicate when certain important validation rules are not met, such as the reconciliation and unjustified negative positions. The intention is to extend this functionality to other reporting profiles in the future, once it has proven to work effectively.

To ensure a correct conversion within DNB to XBRL, it is important that always the most current version of the Excel file from the Reporting Service is used. The submission facility has been developed for Excel files containing fewer than 10,000 rows. Reporting institutions that report more rows should preferably report directly in XBRL format. When using the submission facility, the reporting institution remains responsible for correct and timely delivery of the report.
