In short: You can export your materiality matrix as an image (PNG) and your complete assessment as an Excel file (.xlsx). The Excel file contains your IROs with ratings, your stakeholders, documents, metadata (thresholds and scales) and the audit trail. Exports also work for locked and archived assessments.
1. Export the materiality matrix as an image
- Open your assessment and go to the Results step.
- Set the filters if you only want to show part of the matrix.
- Click Export and choose Matrix image.
The PNG shows the matrix as you see it on screen, including your filters. Use it in presentations, board papers or your sustainability report.

FAQ
Is there a PDF export?
Not at the moment. Use the matrix image together with the Excel file, or the IRO-1 documentation, which you can copy into your report.
Can I export a locked or archived assessment?
Yes. Locked and archived assessments are read-only, but you can always view and export them.
Does the Excel file contain the audit trail?
Yes, the sheet "Audit Trail" lists the changes made to the assessment.
Can I import the Excel file back into Materiality Master?
IROs can be imported under Settings > Import IROs. Note that an import replaces the existing IROs of the assessment.
