Data Considerations
When converting between formats, some data may be lost or unavailable depending on the source and target formats.
Missing Data Without Scryfall
Without the --scryfall flag, transmute only uses data present in the source file. This means:
- Set names may be missing if the source only has set codes (or vice versa)
- Scryfall IDs required by Helvault won't be populated unless present in the source
- Collector numbers may be absent, causing some apps to show generic card images
- Oracle IDs needed for some advanced features won't be available
Using --scryfall enables API lookups to fill these gaps, but adds processing time and requires internet access.
Format-Specific Limitations
| Target Format | Limitation |
|---|---|
| Helvault | Requires scryfall_id - use --scryfall if source lacks it |
| Deckbox | Needs full set names, not codes |
| TCGPlayer | Product ID/SKU only preserved if present in source |
| MTG Manager | Condition/language converted to numeric codes (may lose precision) |
Recommended Workflow
For best results when converting to formats that require rich metadata:
# Use Scryfall to fill missing data
transmute convert collection.csv output.csv -o helvault --scryfall
Python API
You can also use transmute as a library:
from pathlib import Path
from transmute.converter import Converter
from transmute.formats import FormatRegistry
# Convert a file
converter = Converter(use_scryfall=True)
converter.convert(
input_path=Path("collection.csv"),
output_path=Path("output.csv"),
input_format="mtggoldfish",
output_format="manabox",
)
# Read a collection
handler = FormatRegistry.get("helvault")
collection = handler.read(Path("helvault-export.csv"))
for entry in collection:
print(f"{entry.quantity}x {entry.card.name} ({entry.card.set_code})")
