Bulk updating MongoDb documents

Just like SQL Mongo also has a bulk update command. It's as simple as -

           filter: {<your-condition>},
           update: {<what-you-want-to-update>
Enter fullscreen mode Exit fullscreen mode

And the updateOne block can be repeated "n" times.

If you are trying to update from an excel file, use the CONCATENATE().

Here is a sample -

Enter fullscreen mode Exit fullscreen mode

I have values in E2 and F2 columns.
Note: Don't forget the last comma in the CONCATENATE(). Since bulkWrite() accepts an array, it will need the jsons comma separated.

Happy coding :D
