NOTES FOR 2021:
Have redone a bunch of stuff in this for 2021. the Delverlens->Deckbox mode works alright, but the deckbox->cardsphere mode has been completely rewritten.
you want to use mtgconvert2021.py, python mtgconvert2021.py inv.csv delverlens deckbox out.csv
Python script and config files to convert between different CSV export formats of various Magic: the Gathering collection apps and utilities.
Currently built for:
Delver Lens (Deckbox Export) -> Deckbox
Deckbox -> Cardsphere
Deckbox -> Deckbox (this will update all tradelist counts to equal total collection counts and nothing else)
Note this will only convert a file that has the correct csv layout as expected, but differing set or card names - for instance 'Promotional: Non-Release' to a specific set.
Usage
python mtgconvert.py infile inputformat outputformat outfile
infile: the input file
outfile: the output file
inputformat: currently supported: deckbox, delverlens
outputformat: currently supported: deckbox, cardsphere
Example usage:
python mtgconvert.py inv.csv delverlens deckbox out.csv
Config file syntax
Four headings: SET_REPLACE, NAME_REPLACE, NAME_SET_REPLACE, NAME_NUMEBR_REPLACE. These contain replacement rules for all names of a card, all editions, specific name/edition pairs, or alt-art-same-number cards respectively.
A replacement rule for SET_REPLACE or NAME_REPLACE is of the format:
old_name -> new_name
A replacement rule for NAME_SET_REPLACE is of the format:
old_name | old_edition -> new_name | new_edition
The bulk replacement rule for NAME_SET_REPLACE (e.g. for a set of prerelease promos) is of the format:
{ name1 | name2 | ... } | old_edition -> new_edition
The replacement rule for NAME_NUMBER_REPLACE (Alliances, Homelands, Portal for Cardsphere) is of the format:
name | number -> new_name
Intention is for the community to update these replacement files as errors and mismatches are found. Easiest way to add full new set rules is to use a HTML table copier (e.g. Copytables) and text replace tools.
To update finicky things (namely Deckbox->Cardsphere alt-art-same-number cards), it is recommended to check the deckbox collector number and the corresponding CS card name. As these are tedious and low-impact, they will be added as people find them.
