Can't convert object to json in Javascript

I have an object that has fields like the following image:

I want to have it like a plain json object. For example, if the variable name of this was "jitsi", then I should be able to check "displayName" of 155a37bf by coding like "jitsi[0].displayName". It also means that it should output "fwefe" if I code like "console.log(jitsi[0].displayName);".

However, there are so many underbars like _ in every keys.

It also needs to output length. For example, it should output 2 if I code like "console.log(jitsi.length);" as there are 2 entries named "155a37bf" and "908f57df" respectively.

How do I make it like a plain json object?

I already did things like following but it didn't work

 Object.keys(jitsi).map((item) => {
             arr.push({
             category: item,
             ...jsonObj[item]
         })
         });

Thank you very much.

You can convert this object to an array simply by using Object.values().

You can also remove the underscore prefixes using a map operation

// Example data
const jitsi = {
  "155a37bf": {
    _id: "155a37bf",
    _displayName: "fewfe",
  },
  "908f57df": {
    _id: "908f57df",
    _displayName: "sender",
  },
};

// Transform
const jitsiArray = Object.values(jitsi).map((obj) =>
  Object.fromEntries(
    Object.entries(obj).map(([key, val]) => [key.replace(/^_/, ""), val])
  )
);

console.log(jitsiArray);
