A script for mongo shell to get the collection structure.
var conn = new Mongo();
db = conn.getDB(<DB_NAME>);
var cursor = db.<COLLECTION>.find();
var items = [];
items = cursor.toArray();
var dbstruc = {};
for (var i = 0; i < items.length; ++i) {
var target = items[i];
getKP(target,dbstruc);
}
printjson(dbstruc);
function getKP (target,dbstruc) {
for (var k in target) {
if(typeof target[k] !== "object"){
if (target.hasOwnProperty(k) && !dbstruc.hasOwnProperty(k)) {
dbstruc[k] = typeof target[k];
}
}else{
dbstruc[k] = {};
getKP(target[k],dbstruc[k]);
}
}
}

Thanks abt3bs! Glad it helped you 👍

Thanks, it was really useful

For some strange reason, when running with MongoChef 3.5.1 IntelliShell, it errored out:

E QUERY    [thread1] ReferenceError: getKP is not defined :
@(shell):3:3

I had to move getKP() to be before the rest of the code but yes it worked, thanks!
