向 json 文件中的所有项目添加新元素

我有一个文件中的 json 数组：

[
   {
        "id": 2,
        "title": "Mr",  
        "name": "Harry Robinson",
        "company": "ResearchBch",
        "email": "anything",
        "age": 38,
        "startDate": "2015/07/25",
        "salary": "$421069.74"
    },
    ...
]

我想向该数组中的每个项目添加新项目。是否有任何工具或文本编辑器、Notepad++ 插件可用于执行此操作？

假设我想"string": "bla"向每个 json 项插入新属性。

有什么想法吗？

答案1

假设上述格式始终适用：

Ctrl-H
Find what: ([\r\n]+)(\s+)\}
Replace with: ,\1\2\2"string": "bla"\1\2}

答案2

我已经通过链接描述了一种使用 WSH VB 脚本在 Notepad++ 中自动执行操作的方法：在 Notepad++ 中搜索并用结果替换数学运算。该方法允许您为自动操作分配键盘快捷键，并将必要的命令添加到脚本以处理正在编辑的文件。有代码向数组中的每个对象添加一个属性，以 JSON 文件表示：

Option Explicit
Const FileEncoding = 0 ' 0 = ASCII, -1 = Unicode, -2 = System Default

Dim objTokens, strTokenType, bTokenMatched
Dim  strJSONString, varJSON, strState, i

' check if a file path was passed to the script in the only argument
If WScript.Arguments.Count <> 1 then
    CreateObject("WScript.Shell").PopUp "Drop file onto the script", 3, , 48
    WScript.Quit
End If

' read json string from the file
strJSONString = ReadFromFile(WScript.Arguments(0), FileEncoding)

' parse json string
ParseJSON strJSONString, varJSON, strState

' check if root element is an array
If strState <> "Array" Then
    CreateObject("WScript.Shell").PopUp "JSON root element is not an array", 3, , 48
    WScript.Quit
End If

' you can place your own algorithm in this block
' currently it adds a property to each object in array
For i = 0 To UBound(varJSON)
    If IsObject(varJSON(i)) Then ' check if the modified element is an object
        varJSON(i).Add "item", i ' add property
    End If
Next

' serialize json
strJSONString = SerializeJSON(varJSON)

' write json string to the file
WriteToFile strJSONString, WScript.Arguments(0), FileEncoding

CreateObject("WScript.Shell").PopUp "Completed", 1, , 64

Sub ParseJSON(ByVal strContent, varJSON, strState)
    ' strContent - source JSON string
    ' varJSON - created object or array to be returned as result

我已经在 J​​SON 示例上进行了测试：

处理后，“item”属性出现在数组的每个对象中。请注意，源 JSON 字符串是根据以下方式序列化的：ECMA-404 JSON 数据交换标准，因此您可能会发现与源格式有些不同。

        "display": "HTML Tutorial",

尽管项目添加算法在脚本中是硬编码的，但它可以通过轻量级mshtaGUI 设置选项对话框轻松扩展。如果该方法满足您的要求，请告诉我您希望在 GUI 中实现哪些选项、更复杂的修改等。
