ADODB.Stream创建UTF-8+BOM编码的文本文件。
然后遍历数据区，格式化数据，输出即可。
小数据还行，大数据没测试。
另，使用fso创建的文本文件编码为ANSI，ajax解析json时出现乱码无法正常解析。
Sub ToJson() '创建UTF8文本文件 myrange = Worksheets("sheet1").UsedRange '通过有效数据区来选择数据 'myrange = ActiveWorkbook.Names("schoolinfo").RefersToRange '通过定义的名称来选择数据 'myrange = Range(Worksheets("sheet1").Range("a1").End(xlDown), Worksheets("sheet1").Range("a1").End(xlToRight)) '通过标题行的最大行最大列来选择数据 Total = UBound(myrange, 1) '获取行数Fields = UBound(myrange, 2) '获取列数 Dim objStream As Object Set objStream = CreateObject("ADODB.Stream") With objStream .Type = 2 .Charset = "UTF-8" .Open .WriteText "{
""total"":" & Total & ",""contents"":[" For i = 2 To Total .WriteText "{
" For j = 1 To Fields .WriteText """" & myrange(1, j) & """:""" & Replace(myrange(i, j), """", """") & """" If j <> Fields Then .WriteText "," End If Next If i = Total Then .WriteText "}
" Else .WriteText "}

" .SaveToFile ActiveWorkbook.FullName & ".json", 2 End With Set objStream = NothingEnd Sub
最近在写一网站网页,需要从后台ASP网页查询到的MYSQL记录集返回给前台ASP网页,我们知道AJAX是无力从后台返回数据库记录集给前台网页的.
查阅大量资料,就目前而言记录集转换成JSON格式流,再由前台VBA导入WEBoffice控件的excel是个不错的选择.经过些思考,现将function过程代码奉献给大家.
Function GetJSON(Rs) Dim JSON dim returnStr dim i dim oneRecord if Rs.eof=false and Rs.Bof=false then returnStr="{
"&chr(34)&"records"&chr(34)&":[" while Rs.eof=false for i=0 to Rs.Fields.Count -1 oneRecord=oneRecord & chr(34) & Rs.Fields(i).Name & chr(34) &":" oneRecord=oneRecord & chr(34) & Rs.Fields(i).Value & chr(34) &"," Next oneRecord=left(oneRecord,InStrRev(oneRecord,",")-1) oneRecord=oneRecord & "}
," returnStr=returnStr & oneRecord Rs.MoveNext Wend returnStr=left(returnStr,InStrRev(returnStr,",")-1) returnStr=returnStr & "]}
" end if GetJSON=returnStr End Function
