01 Source format
Public sample is ready.
Specification-driven public demonstration
One Tech Pack.
A different format.
This POC converts a public basic-skirt Tech Pack into a different public Excel template. It exposes every mapping decision, preserves where each value came from, and sends uncertainty to review.
What this provesA repeatable conversion mechanism on public data. It does not claim to represent Birdy or any buyer’s private workflow.
Try the conversion
Source in. Evidence out.
The adapter deliberately supports one published source specification. Uploading an unrelated file will fail clearly rather than produce a plausible-looking result.
02 Process
- Verify source specFile identity, format and adapter
- Extract fieldsMetadata, materials, trims and measurements
- NormalizeAliases, units and canonical field names
- Map or escalateConfidence, provenance and exceptions
- Write destinationPublic four-sheet Excel template

Before and after
Same information. Different operating burden.
The comparison is about the handling of evidence, not a claim that every conversion becomes fully automatic.
A merchandiser interprets and re-keys the document.
- Find values across pages and formats
- Decide whether labels mean the same thing
- Copy data into a new template
- Remember what was skipped or assumed
Primary riskSilent interpretation becomes production data.
The specification handles routine mappings and exposes judgment.
- Extract each value with its source location
- Normalize defined aliases and units
- Populate only supported destination fields
- Route mismatches and visual content to review
Primary outcomeA usable destination file plus a traceable exception list.
The conversion specification
The rules are a product asset.
This POC is deterministic. The adapter declares what it accepts, what it can map, and when it must stop.
University of Fashion basic-skirt PDF
Expected metadata labels, measurement rows, three-page structure and file fingerprint.
Product, materials, trims, measurements
Source terminology is normalized without losing the original label or value.
GetTemplated four-sheet Excel Tech Pack
Cells and fields are populated only where the destination meaning is compatible.
Nothing gets silently lost
Unmapped, ambiguous and visual-only content appears in the conversion report.
What the next POC must prove
Public data validates the mechanism.
Partner data validates the business.
The next step is to run the same pipeline on two anonymized incoming Tech Packs and one real downstream template from a buying house. That is where we test coverage, exception rates, review time and operational trust.
