Project Info

Created this tool for my own use since I like to keep my MtG collection up-to-date by using a card scanner.
The best ones I found for this purpose are Manabox and MtG DragonShield Card Manager
You can export data from their site, but there is no easy way to import it to some of the most popular other collection managers such as Moxfield or Deckbox
The other use case, unrelated to card scanners, is to keep your collection in sync across multiple sites
The manual conversion process is quite cumbersome, one always has to replace the corresponding Csv Headers, and replace some values that are slightly different. For example
- Card name: infuriatingly, some sites do not properly encode the full name of double-faced cards, but only front-side.
- Set information: set name or set code missing, non-standard set names
- Foil status;: encoded widely different across formats *Card condition: some sites use a scale of 6, some of 7 conditions. These need to be mapped. Loss of information is inevitable when mapping to lower resolution, though.
- Language: (code vs full name)
- Price: (various formats with various currencies, with or without currency symbol, leading or trailing position)
- etc
Some columns which are not common to most tools are not supported

This tool defines configurable mappings addressing the above issues in appsettings.json

How to use

Browser

A static webapp is available at https://hottemax.github.io/MtgCsvHelper/
As opposed to the console version, there is currently no way to access the configuration (appsettings) and customize the app's behavior
However, it is more user-friendly and should work across a wide range of default scenarios

Console

Prerequisite: Installed .NET Runtime, Version >= 7.0.
You can download from the Releases tab on the right, or you can build from source yourself
- For building from source, unzip the source folde, and run dotnet build in the root directory of the unzipped folder
Run the provided MtgCsvHelper.
- Usage info can be found running it with the --help flag
Some additional configurability for end user via appsettings.json etc.

Troubleshooting

You can report bugs and issues on Github by creating a new issue. After the release of a new version, the browser data/cache should to be cleared to force the new version of the site to be loaded, since static webapps are kept in the browser's cache.

Current state

In appsettings.json, there are a lot of predefined mappings for popular sites
- DRAGONSHIELD
- MOXFIELD
- DECKBOX
- MANABOX
- TCGPLAYER
- MTGGOLDFISH
- CARDKINGDOM
You can add a new configuration for a site that is not yet supported, or even better, create a pull request for it.
The format should be self-documenting. This is an example configuration for MOXFIELD:

"MOXFIELD": {
  "Quantity": "Count",
  "CardName": {
    "HeaderName": "Name",
    "ShortNames": false
  },
  "SetCode": "Edition",
  "SetName": null,
  "SetNumber": "Collector Number",
  "Finish": {
    "HeaderName": "Foil",
    "Normal": "",
    "Foil": "foil",
    "Etched": "etched"
  },
  "Condition": {
    "HeaderName": "Condition",
    "Mint": "Mint",
    "NearMint": "Near Mint",
    "Excellent": "Near Mint",
    "Good": "Good (Lightly Played)",
    "LightlyPlayed": "Played",
    "Played": "Heavily Played",
    "Poor": "Damaged"
  },
  "Language": {
    "HeaderName": "Language",
    "ShortNames": false
  },
  "PriceBought": {
    "HeaderName": "Purchase Price",
    "Currency": "EUR",
    "CurrencySymbol": "Absent"
  }
}

The left hand side of the mappings should be adapted to match the desired format (csv header row)
For some columns, there is additional configuration needed (for example, how the Finish is encoded
For the Condition category, note that different sites use different scales (sometimes 6, sometimes 7 different values, as well as different naming schemes). Hence, there is no canonical mapping
Some formats (e.g. CARDKINGDOM) should not be used for imports, since they contain very few columns

TODOs

Support more formats by popular demand
Add support for token cards (widely different encodings)

Examples:

Token: (TODO)

Moxfield:		"1","1","Clue","tmh2","Near Mint","English","","","2022-11-15 13:00:49.057000","14"
DragonShield:	1,Clue Token,Modern Horizons 2 Tokens,TMH2,14,NearMint,German,Normal
Deckbox:		1,0,Clue,Extras: Modern Horizons 2,14,Near Mint,German,,,,,,,,$0.00

Double-sided: (FIXED)

Moxfield:		"1","1","Ambitious Farmhand // Seasoned Cathar","mid","Near Mint","German","","","2022-11-14 16:57:33.500000","2"
DragonShield:	Other,1,0,Ambitious Farmhand,MID,Innistrad: Midnight Hunt,2,NearMint,Normal,German,0.01,2022-01-29,0.08,0.02,0.14
Deckbox:		1,0,Ambitious Farmhand // Seasoned Cathar,Innistrad: Midnight Hunt,2,Near Mint,German,,,,,,,,$0.00

Basically, we would want to default to Scryfall's syntax (which would mean using the full double-sided name, and omitting the "Token"
