Mixing
Some “ObjectId” is not getting replaced
I am converting the mongodb's document _id
from : "_id" : ObjectId("5c09b6002351d50e100c5f6c"),
To: "_id" : "5c09b6002351d50e100c5f6c",
I am using the regex text.replace(/ObjectId((.*))/gi,"$1");
Issue is some ObjectId gets converted but some doesn't gets converted,don't know why..
small example code of what i am doing:
var fs=require('fs');
var data = fs.readFileSync('./abc.json');
str = data.toString()
str = str.replace(/ObjectId((.*))/g,"$1");
fs.writeFile('str','data.json');
note: I have exported the input file using Studio 3T
Thanks in advance!

You have a problem, then you used regex and now you have two problems.

The problem is your .* also matches some whole "ObjectId(...)" expressions.
A solution is to use a non greedy group:
text.replace(/ObjectId((.*?))/gi,"$1");
A better (more performant) one is to make it explicit if you can:
text.replace(/ObjectId(("[^"]*"))/gi,"$1");
