🔨 CSV export tool for Anki.
leetcode2anki will print CSV data from your LeetCode repository and corresponding question data.
It use SQLite to store LeetCode question data. If data is not exist, it will be fetched from LeetCode API.
Therefore, you need to import CSV to your Anki.
leetcode2anki -lang golang > leetcode.csvIf your LeetCode repository is different from mine, you need to change question and code function in leetcode2anki/main.go:

func question(path string, info os.FileInfo) (leetcode.Key, error) {
if path == "." || !info.IsDir() {

// only handle directory in repository
id, err := strconv.Atoi(path)
if err != nil {
return nil, filepath.SkipDir
}
// identify leetcode question by id
return leetcode.KeyID(id), filepath.SkipDir
}
func code(path string, _ leetcode.Lang) (string, error) {

if err != nil {

}
// start from import declarations, then format code
var w strings.Builder
if err := format.Node(&w, fset, f.Decls); err != nil {

return w.String(), nil
