Import and export

Export a deck

Open the deck menu and choose Export. Pick a format:

• CSV — front, back, and tags separated by commas.
• TSV — the same columns separated by tabs.
• JSON — front, back, type, and tags per card.

The download is generated from the live cards in the deck.

Import cards

1. Open a deck.
2. Choose Import.
3. Upload a CSV, TSV, or JSON file, or paste the content.
4. Choose whether the first row is a header.
5. For delimited files, choose the column delimiter and the tag separator.
6. Review the preview and import.

Delimited format

The first three columns are front, back, and tags:

front,back,tags
la casa,house,spanish;basics
el libro,book,spanish;basics

• delimiter can be a comma, semicolon, tab, or detected automatically.
• tagSeparator controls how tags inside the third column are split (;, ,, or |).
• A header row is optional.

JSON format

[
   { "front": "la casa", "back": "house", "tags": ["spanish", "basics"] },
   { "front": "el libro", "back": "book", "tags": ["spanish", "basics"] }
]

What happens on import

• Rows are capped per import: 500 rows and 1 MB per request.
• A deck holds at most 500 cards. If the import would push the deck past the cap, the whole import is rejected and nothing is written; split the file across decks or delete cards first.
• Repeated fronts in one file are merged: the last row wins, and the import counts each distinct card once.
• Cards are deduplicated by front: an existing card with the same front is updated instead of duplicated.
• Empty rows and malformed rows are reported instead of silently dropped.
• Imported cards are term/definition cards with the source marked as import.
• Tags from the file and the import form are combined, up to 20 tags.

Tips

• Export before a large edit so you have a copy.
• Use tags in the third column to build study subsets.
• Keep one concept per card; long cards are harder to grade.
