Question

我使用以下格式从Mongodb导出了一个JSON文件。我正在尝试从它创建一个数据帧，但我看不到让tidyjson读取它，因为它会抛出此错误。

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

我使用了read_json（“file.json”）

文件在

下面

由于mnogodb产生的这个错误导致＆＃34;扩展＆＃34; json格式。您应该尝试将数据导出为严格的＆＃39; json模式使用，例如，mongoexport（https://docs.mongodb.com/manual/reference/mongodb-extended-json/）

使用tidyjson将R JSON文件转换为Dataframe
