Step 4: Use the below code snippets to export Excel data to JSON format in 3 buttons:
Workbook to JSONThe following code illustrates how to convert an Excel workbook to the JSON file or JSON file stream as schema and without schema. C# using (ExcelEngine excelEngine = new ExcelEngine()) { IApplication application = excelEngine.Excel; application.DefaultVersion = ExcelVersion.Excel2013; IWorkbook workbook = application.Workbooks.Open("Sample.xlsx", ExcelOpenType.Automatic); if (checkBox1.Checked) { //Saves the workbook to a JSON file, as schema by default workbook.SaveAsJson("Excel-Workbook-To-JSON-as-schema-default.json"); //Saves the workbook to a JSON file as schema workbook.SaveAsJson("Excel-Workbook-To-JSON-as-schema.json", true); //Saves the workbook to a JSON filestream, as schema by default FileStream stream = new FileStream("Excel-Workbook-To-JSON-filestream-as-schema-default.json", FileMode.Create); workbook.SaveAsJson(stream); //Saves the workbook to a JSON filestream as schema FileStream stream1 = new FileStream("Excel-Workbook-To-JSON-filestream-as-schema.json", FileMode.Create); workbook.SaveAsJson(stream1, true); } else { //Saves the workbook to a JSON file without schema workbook.SaveAsJson("Excel-Workbook-To-JSON-without-schema.json", false); //Saves the workbook to a JSON filestream without schema FileStream stream = new FileStream("Excel-Workbook-To-JSON-filestream-without-schema.json", FileMode.Create); workbook.SaveAsJson(stream, false); } }
VB.NET Using excelEngine As ExcelEngine = New ExcelEngine() Dim application As IApplication = excelEngine.Excel application.DefaultVersion = ExcelVersion.Excel2013 Dim workbook As IWorkbook = application.Workbooks.Open("Sample.xlsx", ExcelOpenType.Automatic) If CheckBox1.Checked Then 'Saves the workbook to a JSON file, as schema by default workbook.SaveAsJson("Excel-Workbook-To-JSON-as-schema-default.json") 'Saves the workbook to a JSON file as schema workbook.SaveAsJson("Excel-Workbook-To-JSON-as-schema.json", True) 'Saves the workbook to a JSON filestream as schema by default Dim stream As FileStream = New FileStream("Excel-Workbook-To-JSON-filestream-as-schema-default.json", FileMode.Create) workbook.SaveAsJson(stream) 'Saves the workbook to a JSON filestream as schema Dim stream1 As FileStream = New FileStream("Excel-Workbook-To-JSON-filestream-as-schema.json", FileMode.Create) workbook.SaveAsJson(stream1, True) Else 'Saves the workbook to a JSON file without schema workbook.SaveAsJson("Excel-Workbook-To-JSON-without-schema.json", False) 'Saves the workbook to a JSON filestream without schema Dim stream As FileStream = New FileStream("Excel-Workbook-To-JSON-filestream-without-schema.json", FileMode.Create) workbook.SaveAsJson(stream, False) End If End Using
Worksheet to JSONThe following code illustrates how to convert an Excel worksheet to the JSON file or JSON file stream with schema and without schema. C# using (ExcelEngine excelEngine = new ExcelEngine()) { IApplication application = excelEngine.Excel; application.DefaultVersion = ExcelVersion.Excel2013; IWorkbook workbook = application.Workbooks.Open("Sample.xlsx", ExcelOpenType.Automatic); //Active worksheet IWorksheet worksheet = workbook.Worksheets[0]; if(checkBox1.Checked) { //Saves the worksheet to a JSON file, as schema by default workbook.SaveAsJson("Excel-Worksheet-To-JSON-as-schema-default.json", worksheet); //Saves the worksheet to a JSON file as schema workbook.SaveAsJson("Excel-Worksheet-To-JSON-as-schema.json", worksheet, true); //Saves the worksheet to a JSON filestream, as schema by default FileStream stream = new FileStream("Excel-Worksheet-To-JSON-filestream-as-schema-default.json", FileMode.Create); workbook.SaveAsJson("stream", worksheet); //Saves the worksheet to a JSON filestream as schema FileStream stream1 = new FileStream("Excel-Worksheet-To-JSON-filestream-as-schema.json", FileMode.Create); workbook.SaveAsJson(stream1, worksheet, true); } else { //Saves the worksheet to a JSON file without schema workbook.SaveAsJson("Excel-Worksheet-To-JSON-without-schema.json", worksheet, false); //Saves the worksheet to a JSON filestream without schema FileStream stream = new FileStream("Excel-Worksheet-To-JSON-filestream-without-schema.json", FileMode.Create); workbook.SaveAsJson(stream, worksheet, false); } }
VB.NET Using excelEngine As ExcelEngine = New ExcelEngine() Dim application As IApplication = excelEngine.Excel application.DefaultVersion = ExcelVersion.Excel2013 Dim workbook As IWorkbook = application.Workbooks.Open("Sample.xlsx", ExcelOpenType.Automatic) 'Active worksheet Dim worksheet As IWorksheet = workbook.Worksheets(0) If CheckBox1.Checked Then 'Saves the worksheet to a JSON file, as schema by default workbook.SaveAsJson("Excel-Worksheet-To-JSON-as-schema-default.json", worksheet) 'Saves the worksheet to a JSON file as schema workbook.SaveAsJson("Excel-Worksheet-To-JSON-as-schema.json", worksheet, True) 'Saves the worksheet to a JSON filestream as schema by default Dim stream As FileStream = New FileStream("Excel-Worksheet-To-JSON-filestream-as-schema-default.json", FileMode.Create) workbook.SaveAsJson(stream, worksheet) 'Saves the worksheet to a JSON filestream as schema Dim stream1 As FileStream = New FileStream("Excel-Worksheet-To-JSON-filestream-as-schema.json", FileMode.Create) workbook.SaveAsJson(stream1, worksheet, True) Else 'Saves the worksheet to a JSON file without schema workbook.SaveAsJson("Excel-Worksheet-To-JSON-without-schema.json", worksheet, False) 'Saves the worksheet to a JSON filestream without schema Dim stream As FileStream = New FileStream("Excel-Worksheet-To-JSON-filestream-without-schema.json", FileMode.Create) workbook.SaveAsJson(stream, worksheet, False) End If End Using
Range to JSONThe following code illustrates how to convert an Excel Custom Range to the JSON file or JSON file stream as schema and without schema. C# using (ExcelEngine excelEngine = new ExcelEngine()) { IApplication application = excelEngine.Excel; application.DefaultVersion = ExcelVersion.Excel2013; IWorkbook workbook = application.Workbooks.Open("Sample.xlsx", ExcelOpenType.Automatic); //Active worksheet IWorksheet worksheet = workbook.Worksheets[0]; //Custom range IRange range = worksheet.Range["A2:A5"]; if(checkBox1.Checked) { //Saves the range to a JSON file, as schema by default workbook.SaveAsJson("Excel-Range-To-JSON-as-schema-default.json", range); //Saves the range to a JSON file as schema workbook.SaveAsJson("Excel-Range-To-JSON-as-schema.json", range, true); //Saves the range to a JSON filestream, as schema by default FileStream stream = new FileStream("Excel-Range-To-JSON-filestream-as-schema-default.json", FileMode.Create); workbook.SaveAsJson(stream, range); //Saves the range to a JSON filestream as schema FileStream stream1 = new FileStream("Excel-Range-To-JSON-filestream-as-schema.json", FileMode.Create); workbook.SaveAsJson(stream1, range, true); } else { //Saves the range to a JSON file without schema workbook.SaveAsJson("Excel-Range-To-JSON-without-schema.json", range, false); //Saves the range to a JSON filestream without schema FileStream stream = new FileStream("Excel-Range-To-JSON-filestream-without-schema.json", FileMode.Create); workbook.SaveAsJson(stream, range, false); } }
VB.NET Using excelEngine As ExcelEngine = New ExcelEngine() Dim application As IApplication = excelEngine.Excel application.DefaultVersion = ExcelVersion.Excel2013 Dim workbook As IWorkbook = application.Workbooks.Open("Sample.xlsx", ExcelOpenType.Automatic) 'Active worksheet Dim worksheet As IWorksheet = workbook.Worksheets(0) 'Custom range Dim range As IRange = worksheet.Range("A2:A5") If CheckBox1.Checked Then 'Saves the range to a JSON file, as schema by default workbook.SaveAsJson("Excel-Range-To-JSON-as-schema-default.json", range) 'Saves the range to a JSON file as schema workbook.SaveAsJson("Excel-Range-To-JSON-as-schema.json", range, True) 'Saves the range to a JSON filestream, as schema by default Dim stream As FileStream = New FileStream("Excel-Range-To-JSON-filestream-as-schema-default.json", FileMode.Create) workbook.SaveAsJson(stream, range) 'Saves the range to a JSON filestream as schema Dim stream1 As FileStream = New FileStream("Excel-Range-To-JSON-filestream-as-schema.json", FileMode.Create) workbook.SaveAsJson(stream1, range, True) Else 'Saves the range to a JSON file without schema workbook.SaveAsJson("Excel-Range-To-JSON-without-schema.json", range, False) 'Saves the range to a JSON filestream without schema Dim stream As FileStream = New FileStream("Excel-Range-To-JSON-filestream-without-schema.json", FileMode.Create) workbook.SaveAsJson(stream, range, False) End If End Using
