Yes, AnkiApp can import decks from spreadsheet files, in CSV (comma-separated value) or TSV (tab-separated value) format, which can be exported from a wide variety of software. AnkiApp additionally supports including sounds and images in these decks, by referencing those files from the CSV/TSV, and putting them all together in a .zip file.
Creating Line Breaks in Imported Decks
Anywhere that you would like to have a line break occur in the resulting deck, include this text "<br/>" in your CSV/TSV file.
Making a CSV/TSV file with Excel
To save an Excel spreadsheet as CSV or TSV, please see http://office.microsoft.com/en-us/excel-help/import-or-export-text-txt-or-csv-files-HP010099725.aspx.
For an example of a basic deck with five cards and text "front" and "back", see the attached .CSV file Example_AnkiApp_Basic_Deck.csv.
Example with Sounds and Images
For an example of how to import a deck that includes sounds and images, see the attached zip file Example_AnkiApp_TSV_Deck.zip.
Make sure the .CSV/.TSV is exported/saved in UTF-8/16 encoding to preserve international character support.
- download the example,
- unzip it,
- edit to suit your needs, then
- zip it back up, and
- import it.
