Summary

Extracts the heading outline from a document URL using ONLYOFFICE Document Builder. Returns each paragraph styled with a heading level as a separate n8n item.

Inputs

  • File URL (builderFileUrl) (required) — URL of the input document; it must be reachable from the ONLYOFFICE Document Server. Use {{ $json.outputUrl }} to pass a URL from a previous Document Builder step.

Output shape

A list of items, one per detected heading, each with level, text, and index fields.

The operation recognizes paragraph styles whose names start with Heading or heading and contain a number; that number becomes level. It returns an empty list if none are found. The source document is opened in Document Builder, and the outline JSON is saved as a temporary text output that the node reads and parses.
