How to correctly implement a VBA function that reads and modifies a JSON file in Excel?
Could someone explain I'm working on a personal project and I'm trying to create a VBA function in Excel that reads data from a JSON file, modifies that data, and then writes it back to the same file. However, I'm running into issues with the JSON parsing and the writing process. I’ve been using the `JsonConverter.bas` library for parsing JSON, but I keep getting errors, and I'm not sure if I'm managing file reads and writes correctly. Here’s a portion of my code: ```vba Sub UpdateJsonFile() Dim jsonFile As String Dim jsonText As String Dim jsonData As Object Dim fso As Object Dim ts As Object jsonFile = "C:\path\to\your\file.json" Set fso = CreateObject("Scripting.FileSystemObject") Set ts = fso.OpenTextFile(jsonFile, 1) ' 1 = ForReading jsonText = ts.ReadAll ts.Close Set jsonData = JsonConverter.ParseJson(jsonText) ' Example modification jsonData("key1") = "new value" ' Writing back to the file Set ts = fso.OpenTextFile(jsonFile, 2) ' 2 = ForWriting ts.Write JsonConverter.ConvertToJson(jsonData) ts.Close End Sub ``` When I run this code, it throws a `Run-time behavior '53': File not found` behavior, even though the path to the JSON file is correct. I've double-checked the file path and made sure that the file exists. Also, I’m not sure if I’m correctly converting the JSON object back to a string before writing it. Additionally, is there a best practice for handling file access rights, as I might encounter permission issues on certain systems? Any suggestions on how to properly implement this function or debug the issues I’m working with would be greatly appreciated. I'm using Excel 2016 on Windows 10. I'm working on a application that needs to handle this. I recently upgraded to Vba 3.9.
