Mongodb - Mongoimport error invalid character

Question

I tried to import a simple json file using mongoimport and i get the following error

PER-MacBook-Pro:/AJ$ mongoimport --db test --collection samplePM --file         


        

Answer 1

I was getting Failed: error processing document #112783: invalid character ',' looking for beginning of value because one of my objects was formatted improperly. Notice how "psychosurgery" is missing curly braces:

{
  "word": "psychosurgeons",
  "firstLetter": "p"
}
  " psychosurgery",
{
  "word": "psychosurgical",
  "firstLetter": "p"
}

Since there are over 600,000 lines in the file I'm trying to import, this would have been tough to find manually.

So I ran the same mongoimport command with full verbosity (-vvvvv) enabled, and the script stopped right on the problematic object. See mongoimport --help for more info.

Hope this helps someone.
