How it works

How it works

  1. 01

    Upload

    Drop a PDF or DOCX annual report. Doc2iXBRL extracts statements and disclosures.

  2. 02

    Review

    Confirm the filing profile, correct concept assignments, and add extensions where needed. Consolidated and company statements stay distinct so each set is mapped against its own filing rules.

  3. 03

    Validate

    Generate iXBRL. Arelle runs full specification validation. Pre-validation and an auto-fix pass catch common FR-NL and ESEF errors before final output.

  4. 04

    Export

    Download a submission-ready report package, with the bundled assets the destination filing portal expects.

Built for control

Built for control

Professional judgement, not full automation

Every concept assignment, extension, and disclosure block is reviewable. AI suggests, the user decides.

Validation that mirrors the filing authority

Arelle runs the same spec the regulators do. Validation passing is a strong signal, but not a guarantee of filing acceptance: KVK, AFM, and ESMA may apply additional submission-time checks.

Secure infrastructure with EU-hosted storage

Documents and conversions live in EU-region Supabase Storage. Encryption in transit and at rest. DPA and sub-processor materials available on request.
