尝试拉取json数据但不能拉取json数据对象 浪费了1天来解决这个问题，但我得到 org.json.JSONArray无法转换为JSONObject
这是什么错误？任何一个面临相同的问题让我知道阵列数组 下面是我试过的代码。
在谷歌搜索没有得到解决方案
更新 我得到所有数据中的所有数组Array都在相同的输出ExerciseChapters。可以查看“我正在输出”的输出
json输出了我正在做的错误

尝试像这样获取数组
Dim objCon, objRs
set objCon = createobject("ADODB.Connection")
objCon.Open "Provider = Microsoft.ACE.OLEDB.12.0;" & "Data Source = O:\Desktop\UFT\Testcases.xlsx;" & "Extended Properties = ""Excel 12.0 Xml;HDR = YES;"";"
Set objRs = createobject("ADODB.Recordset")
objRs.Open "select count(*) from Sheet1 where status = 'Fail'", objcon
msgbox objRs(0)
Set objCon = nothing
Set objRs = nothing
