ElasticSearch returns full index to csv file

Question

Is it possible to easily export whole index(all saved fields) an elasticsearch cluster in a file .csv(possibly out of the box)?

An alternative I can imagine is to query the entire index and then convert the result ... but I really don't like the idea of ​​parsing the monstrous json, as it contains several million documents!

Are there any other ways or ideas to export?
