Save/Load Data using Json File(Json Serialization/Deserialization)

WeaponData.cs

//Object of this class will hold the data
//And then this object will be converted to JSON
[System.Serializable]
public class WeaponData
{
    public string Id;
    public string Name;
    public string Information;
}

JsonReadWriteSystem.cs

using System.IO;
using UnityEngine;
using UnityEngine.UI;

public class JsonReadWriteSystem : MonoBehaviour
{
    public InputField idInputField;
    public InputField nameInputField;
    public InputField infoInputField;

    public void SaveToJson()
    {
        WeaponData data = new WeaponData();
        data.Id = idInputField.text;
        data.Name = nameInputField.text;
        data.Information = infoInputField.text;

        string json = JsonUtility.ToJson(data, true);
        File.WriteAllText(Application.dataPath + "/WeaponDataFile.json", json);
    }

    public void LoadFromJson()
    {

    {
        TextEditor textEditor = new TextEditor();
        textEditor.multiline = true;
        textEditor.Paste();  //Copy string from Clipboard to textEditor.text
        inputField.text = textEditor.text;

Save & Load Data Securely Using BinaryFormatter

PlayerData.cs

//Container to hold data
[System.Serializable]

{
    public InputField nameInputField;
    public Slider ageSlider;
    public Dropdown classDropdown;

    //Path where data file will be stored
    string filePath;

    void Awake()
    {
        filePath = Path.Combine(Application.dataPath, "playerData.dat");
    }

    public void SavePlayerData()
    {
        PlayerData playerData = new PlayerData();
        playerData.playerName = nameInputField.text;
        playerData.playerAge = ageSlider.value;
        playerData.playerClass = classDropdown.value;

        Stream stream = new FileStream(filePath, FileMode.Create);
        BinaryFormatter binaryFormatter = new BinaryFormatter();
        binaryFormatter.Serialize(stream, playerData);
        stream.Close();
    }

    public void LoadPlayerData()
    {
        if(File.Exists(filePath))
        {
            Stream stream = new FileStream(filePath, FileMode.Open);
            BinaryFormatter binaryFormatter = new BinaryFormatter();
            PlayerData data = (PlayerData)binaryFormatter.Deserialize(stream);
            stream.Close();

            nameInputField.text = data.playerName;
            ageSlider.value = data.playerAge;
            classDropdown.value = data.playerClass;
        }
