Load, Edit & Save Multi-tab Spreadsheet

//1. Get a path to the input file (or stream with file content).
//In this case it is sample XLSX (OOXML) with two tabs.
string inputFilePath = Constants.SAMPLE_XLSX;

//2. Load it into Editor instance from stream
using (FileStream inputStream = File.OpenRead(inputFilePath))
{
    using (Editor editor = new Editor(delegate { return inputStream;}, delegate { return new SpreadsheetLoadOptions();}))
    {
        //3. Let's create an intermediate EditableDocument from 1st tab
        SpreadsheetEditOptions editOptions1 = new SpreadsheetEditOptions();
        editOptions1.WorksheetIndex = 0;//index is 0-based
        EditableDocument firstTabBeforeEdit = editor.Edit(editOptions1);

        //4. Let's create an intermediate EditableDocument from 2nd tab
        SpreadsheetEditOptions editOptions2 = new SpreadsheetEditOptions();
        editOptions2.WorksheetIndex = 1;//index is 0-based
        EditableDocument secondTabBeforeEdit = editor.Edit(editOptions2);

        //5. Save first tab from EditableDocument #1 to separate document
        SpreadsheetSaveOptions saveOptions1 = new SpreadsheetSaveOptions(SpreadsheetFormats.Xlsm);
        string outputFilename1 = Path.GetFileNameWithoutExtension(inputFilePath) + "_tab1.xlsm";
        string outputPath1 = Path.Combine(Constants.GetOutputDirectoryPath(), outputFilename1);
        editor.Save(firstTabBeforeEdit, outputPath1, saveOptions1);

        //6. Save second tab from EditableDocument #2 to separate document
        SpreadsheetSaveOptions saveOptions2 = new SpreadsheetSaveOptions(SpreadsheetFormats.Xlsb);
        string outputFilename2 = Path.GetFileNameWithoutExtension(inputFilePath) + "_tab2.xlsb";
        string outputPath2 = Path.Combine(Constants.GetOutputDirectoryPath(), outputFilename2);
        editor.Save(secondTabBeforeEdit, outputPath2, saveOptions2);

        //7. Dispose both EditableDocument instances
        firstTabBeforeEdit.Dispose();
        secondTabBeforeEdit.Dispose();
    }
