Planned Support
- Document structure extraction
- Metadata recovery
- Content extracted to text
- Export to CSV, Excel, JSON, and SQL
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 convert 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 (omitted for tables over 1,048,575 rows, 16,384 columns or 8,000,000 cells - see note below) |
xls/{TableName}.xls | Legacy Excel format per table (omitted for tables over 65,535 rows, 256 columns or 150,000 cells - see note below) |
json/{TableName}.json | JSON array of records per table |
json/{TableName}.jsonl | Newline-delimited JSON (streaming-friendly) |
postgres.sql | PostgreSQL CREATE TABLE + INSERT statements |
mysql.sql | The same schema and rows, in MySQL dialect |
sqlite.sql | The same schema and rows, in SQLite dialect |
ansi.sql | The same schema and rows, in portable ANSI SQL |
sqlserver.sql | The same schema and rows, in SQL Server (T-SQL) dialect |
report.json | Structured conversion report |
report.md | Human-readable conversion 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.
Note on the Excel formats. An
.xlsxsheet holds at most 1,048,575 rows of data and 16,384 columns, and a legacy.xlssheet 65,535 rows and 256 columns. Rather than ship a file that looks complete but is silently cut short, DataMeans leaves a table out of any Excel format it does not fit and notes it in the job report. The.xlsxcopy is also left out for tables of more than 8,000,000 cells (1,048,575 rows of 12 columns is 12.6 million), which take too long and too much memory to write, and the.xlscopy for tables of more than 150,000 cells, which the legacy format takes far too long to write. The CSV, JSON and SQL outputs always contain every row.
Overview
Documentation coming soon.
This article will contain vendor-neutral technical documentation about the Interleaf document publishing format, including:
- History and background
- File format specifications
- Data types and structures
- Version differences
- Technical references
Not available for hosted uploads yet. The parser is in development.
Can I convert Interleaf databases with DataMeans today?
Not yet. Interleaf is not available for self-serve upload, and support is still in development. Get in touch and we'll tell you where it stands and help plan the migration.
What will DataMeans convert Interleaf databases to?
Once Interleaf is available, exports will match every other system we support: clean CSV, Excel, JSON & SQL, one file per table, with a structured report of exactly what was extracted.
Is my data secure?
Yes. Your files are encrypted in transit and at rest, and they're deleted automatically: within 7 days if you don't go ahead with a conversion, and when your download window ends if you do. We never sell or share your data, and we never use it to train machine-learning models.
