- Upload Interleaf files
Guide
Interleaf is a document-centric database system focused on technical documentation management with hierarchical structure and embedded formatting.
Planned Support
- Interleaf/ISOGEN versions 3.x through 4.x
- Document structure extraction
- Metadata recovery
- Content extraction to text format
What You Get Out
Once the parser ships, DataMeans will extract your data into multiple modern formats:
| Output | Description |
|---|---|
csv/{TableName}.csv | One CSV file per table with all row data |
xlsx/{TableName}.xlsx | Excel workbook per table |
xls/{TableName}.xls | Legacy Excel format per table |
json/{TableName}.json | JSON array of records per table |
json/{TableName}.jsonl | Newline-delimited JSON (streaming-friendly) |
postgres.sql | PostgreSQL CREATE TABLE + INSERT statements |
schema/schema-graph.json | Relationship graph for visualization |
schema/er-model.json | ER model for diagram tools |
report.json | Structured extraction report |
report.md | Human-readable extraction summary |
File Requirements
- Interleaf/ISOGEN document files
Current Status
Parser development is in the planning phase. The company is defunct, making documentation acquisition difficult.
Technical Notes
This is a document-centric rather than data-centric format. The proprietary binary format with embedded formatting adds complexity to extraction.
