How to export data to multiple Excel spreadsheets?


How can I export fields to different sheets of a single Excel file?


Export to different sheets of an Excel workbook can be configured using script export.

Below is a C# sample of such custom export to Excel. It exports data to different sheets depending on the value of one of the fields  - FieldDocType. 

It is required to attach Microsoft.Office.Interop.Excel.dll as .NET reference in Document Definition properties > .NET References:


using Excel = Microsoft.Office.Interop.Excel;

//Start Excel and get Application object
Excel.Application excelApp = new Excel.Application();
excelApp.Visible = true;

//open Workbook from the specified path
string path = @"\\localhost\export\test.xlsx";  
System.Reflection.Missing misVal = System.Reflection.Missing.Value;
Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(path, misVal,misVal,misVal,misVal,misVal,

// Sheets 
string[] SheetName = {"Sheet1", "Sheet2", "Sheet3"};
Excel.Worksheet currentSheet = (Excel.Worksheet)excelWorkbook.Sheets[SheetName[0]];

// columns order
string[] columns = {"Document Section 1\\Field4", 
                    "Document Section 1\\Field1",
                    "Document Section 1\\Field3", 
                    "Document Section 1\\Field2"};
// Saving to different sheets depending on FieldDocType field value 
if (Document.Field("Document Section 1\\FieldDocType").Text == "01") 
    currentSheet = (Excel.Worksheet)excelWorkbook.Sheets[SheetName[0]];
else if (Document.Field("Document Section 1\\FieldDocType").Text == "02")
    currentSheet = (Excel.Worksheet)excelWorkbook.Sheets[SheetName[1]];
else         //if (Document.Field("Document Section 1\\FieldDocType").Text == "03")
    currentSheet = (Excel.Worksheet)excelWorkbook.Sheets[SheetName[2]];

// Figuring out the last used row of the sheet
Excel.Range last = currentSheet.Cells.SpecialCells(Excel.XlCellType.xlCellTypeLastCell, misVal);
int lastUsedRow = last.Row;    

// Saving field values to current sheet after the last row
for (int cell_y=0; cell_y<columns.Length; cell_y++) {
    currentSheet.Cells[lastUsedRow+1, (cell_y+1)] = Document.Field(columns[cell_y]).Text;

// Save and close .xlsx

    Hi Tatiana,,

    First of all, thank you for your contribution.
    I have a problem, it won't let me add the dll by , I have added it as a DLL in a file. It gives me an error:
    System.IO.FileNotFoundException: Cannot load file or assembly 'office, Version=16.0 .0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the specified file. File name: 'office, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c' in Main.Execute(IDocument Document, IProcessingCallback Processing) AVS: Assembly link registration is disabled. To enable assembly link error logging, set the [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) registry value to 1. Note: There is a performance decrease associated with assembly link error logging. To disable this feature, delete the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
