How to parse JSON with VBA without external libraries?
I've found this script example useful (from http://www.mrexcel.com/forum/excel-questions/898899-json-api-excel.html#post4332075 ):
Sub getData() Dim Movie As Object Dim scriptControl As Object Set scriptControl = CreateObject("MSScriptControl.ScriptControl") scriptControl.Language = "JScript" With CreateObject("MSXML2.XMLHTTP") .Open "GET", "http://www.omdbapi.com/?t=frozen&y=&plot=short&r=json", False .send Set Movie = scriptControl.Eval("(" + .responsetext + ")") .abort With Sheets(2) .Cells(1, 1).Value = Movie.Title .Cells(1, 2).Value = Movie.Year .Cells(1, 3).Value = Movie.Rated .Cells(1, 4).Value = Movie.Released .Cells(1, 5).Value = Movie.Runtime .Cells(1, 6).Value = Movie.Director .Cells(1, 7).Value = Movie.Writer .Cells(1, 8).Value = Movie.Actors .Cells(1, 9).Value = Movie.Plot .Cells(1, 10).Value = Movie.Language .Cells(1, 11).Value = Movie.Country .Cells(1, 12).Value = Movie.imdbRating End With End WithEnd Sub
Call me simple but I just declared a Variant and split the responsetext from my REST GET on the quote comma quote between each item, then got the value I wanted by looking for the last quote with InStrRev. I'm sure that's not as elegant as some of the other suggestions but it works for me.
varLines = Split(.responsetext, """,""") strType = Mid(varLines(8), InStrRev(varLines(8), """") + 1)
There are two issues here. The first is to access fields in the array returned by your JSON parse, the second is to rename collections/fields (like sentences) away from VBA reserved names.
Let's address the second concern first. You were on the right track. First, replace all instances of sentences
with jsentences
If text within your JSON also contains the word sentences, then figure out a way to make the replacement unique, such as using "sentences":[
as the search string. You can use the VBA Replace
method to do this.
Once that's done, so VBA will stop renaming sentences to Sentences, it's just a matter of accessing the array like so:
'first, declare the variables you need:Dim jsent as Variant'Get arr all setup, thenFor Each jsent in arr.jsentences MsgBox(jsent.orig)Next
