Экспорт CouchDB базы данных CSV

Я достаточно использовать RDB и не имеют никакого опыта о REST или программировании ..Экспорт CouchDB базы данных CSV

Я обычно работаю с MSSQL и первенствовать ...

Существует некоторая база данных по CouchDB что я хочу экспортировать в Excel.

Как я могу экспортировать базу данных в csv?

Вот пример источника первого документа.

Y ou сказал, что вы пытались повторно использовать существующий «список». Тем не менее, 'list' должен быть применен к' view', еще вы написали 'view'? –

Используйте инструмент браузера, чтобы получить CSV из результата JSON. Вот источник:
