使用tidyjson将JSON文件转换为Dataframe [英] R JSON File to Dataframe using tidyjson

问题描述

我从Mongodb以以下格式导出了JSON文件.我正在尝试从中创建一个数据框，但看不到tidyjson来读取它，因为它会引发此错误.

I exported a JSON file from Mongodb with the below format. I'm trying to create a dataframe from it but I can't see to get tidyjson to read it as it throws this error.

Error: lexical error: invalid char in json text.
                        {      "_id" : ObjectId("586e684427a06a4a658fa
                     (right here) ------^

我使用了read_json("file.json")

I used read_json("file.json")

文件在下面

推荐答案

由于mnogodb产生的这种错误会产生扩展的" json格式.您应该尝试使用"mongoexport(

This error due to mnogodb produce "extended" json format. You should try to export your data in 'strict' json mode using, for example, mongoexport (https://docs.mongodb.com/manual/reference/mongodb-extended-json/)
