Excel表格是我們?nèi)粘I钪薪?jīng)常用到的工具之一,而Json是一種輕量級的數(shù)據(jù)交換格式,廣泛應(yīng)用于前后端數(shù)據(jù)交互、API等多個領(lǐng)域。如何將Excel表格生成Json格式的數(shù)據(jù)呢?下面我們來一起探討一下。
首先,在Excel表格中,我們需要給各個字段進行命名,這個命名就是后續(xù)生成Json數(shù)據(jù)的key值。然后,我們通過Excel VBA編寫宏程序,將數(shù)據(jù)讀取到Excel VBA的數(shù)據(jù)結(jié)構(gòu)中,再通過循環(huán)遍歷的方式,將讀取到的數(shù)據(jù)轉(zhuǎn)化成Json格式。
Sub ExcelToJson() Dim i As Integer, j As Integer, s As String Dim dict, rows Set dict = CreateObject("Scripting.Dictionary") Set rows = CreateObject("Scripting.Dictionary") For i = 1 To ActiveSheet.Cells(1, Columns.Count).End(xlToLeft).Column dict.Add ActiveSheet.Cells(1, i).Text, i Next i For i = 2 To ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row s = "{" For j = 1 To dict.Count s = s & """" & dict.Keys(j - 1) & """:""" & ActiveSheet.Cells(i, dict.Items(j - 1)).Text & """" If j< dict.Count Then s = s & "," Next j s = s & "}" rows.Add i, s Next i s = "[" For i = 1 To rows.Count s = s & rows.Items(i - 1) If i< rows.Count Then s = s & "," Next i s = s & "]" MsgBox s End Sub
上面的代碼可以將Excel表格中的數(shù)據(jù)生成為Json格式,其中需要注意的是,在VBA中生成Json數(shù)據(jù),最后需要將生成的Json數(shù)據(jù)賦值給某個變量、控件或者打印出來等操作。
總之,通過Excel表格生成Json數(shù)據(jù)是一項很有實際應(yīng)用價值的技術(shù),我們可以通過VBA編寫宏程序,將Excel表格中的數(shù)據(jù)轉(zhuǎn)化為Json格式,實現(xiàn)前后端數(shù)據(jù)交互、API等多種需求。
