JSON Question

Mongoimport of json file

I have a json file consisting of about 2000 records. Each record which will correspond to a document in the mongo database is formatted as follows:

execModify: new Date("Fri May 11 15:05:42 2012"),
startTime: new Date("Thu May 31 15:59:39 2012"),

Each record is on a single line in the JSON file, and the only line breaks are at the end of every record. Therefore, each line in the document starts with "{jobID:"... I am trying to import these into a mongo database using the following command:

mongoimport --db dbName --collection collectionName --file fileName.json

However, I get the following error:

I do not know what the problem is. Can someone please recommend a solution? Thanks so much for your time!

I was able to fix the error using the following query:

    mongoimport --db taac --collection july2012 lariatData-sgeT-2012-07-02.json --jsonArray

Hopefully this is helpful to someone.
