I did attempt this. I had to parse the json manually. This is how far I got:

import stdlib.*;
import stdlib.path.*;

struct Post {
  _id str;
  title str;
  tags List<str>;
}

func contains(haystack str, needle str) bool {
  i = 0;
  while i <= haystack.len() - needle.len() {
    // Extract a substring of the same length as the needle
    substring = haystack.slice(i, i + needle.len());

    // Check if the substring matches the needle
    if substring == needle {
      return true; // Found a match
    }

    i = i + 1;
  }

    return false; 
}

func combineTags(parts List<str>) List<str> {
    isTitleOrID = (s str) => {s.contains("_id") or s.contains("title")};
    result = List<str>();

    allTags = "";

    foreach s in parts {
        if isTitleOrID(s) {
            result.add(s);
        }else {
            allTags = allTags + s;
        }
    }

    result.add(allTags);

    return result;
}

func cleanUp(input str) str{
    r1 = "{";
    r2 = "}";
    r3 = "\"";
    r4 = "[";
    r5 = "]";
    return input.replaceAll(r1,"").replaceAll(r2,"").replaceAll(r3,"").replaceAll(r4,"").replaceAll(r5,"").trim();
}

func findValue(kvPairs List<(str, str)>, key str) str {
    foreach [k, v] in kvPairs {
        if k == key {
            return v;
        }
    }
    return "";
}

func parsePost(input str) Post{
    elements_temp = input.split(",");
    elements = combineTags(elements_temp);
    kvpairs = List<(str, str)>();

    foreach s in elements {
        parts = s.split(":");
        key = parts[0].cleanUp();
        value = parts[1].cleanUp();
        kvpairs.add((key, value));
    }

    tags = kvpair.findValue("tags").split(",").map((s) => s.trim());
    return Post(kvpair.findValue("_id"), kvpair.findValue("title"), tags);
}


func parseJson(input str) List<Post> {
    json = input.slice(1,input.len() - 1);
    separator = """},""";
    objects = json.split(separator);

    result = List<Post>();

    foreach s in objects {
        result.add(parsePost(s));
    }

    return result;
}

exported func main() {
    contents = readFileAsString("../demo.vale");
    // trimmed = contents.slice(1, contents.len() - 1);
    println( contents.len() );

    jsonString = """
            [
