Convert Word docx to Excel using OpenXML

Question

Is there any way to convert Word document where I have some tables into Excel file? It would be very helpful to convert tables.

Something like that:

• Open Word document using OpenXML
• Find all tables xml-tags
• Copy xml-tags
• Create Excel file
• Insert xml-tags with table from Word to new Excel file

I mean

void OpenWordDoc(string filePath)
{
_documentWord = SpreadsheetDocument.Open(filePath, true);
}

List<string> GetAllTablesXMLTags()
{
//find and copy
}

List<string> CreateExcelFile(string filePath)
{
TemplateExcelDocument excelDocument = new TemplateExcelDocument();
_documentExcel = excelDocument.CreatePackage(filePath);
}

void InsertXmlTagsToExcelFile(string filePath)
{
CreateExcelFiles(filePath);
var xmlTable = GetAllTablesXMLTags();
// ... insert to _documentExcel
}

Answer 1

your steps are correct.

I would like to share some sdk documents, hope it could help to some extent:

Open XML SDK 2.5 for Office

When handling the word tables:

Working with WordprocessingML tables (Open XML SDK)

When processing excel tables:

Working with the shared string table (Open XML SDK)

Working with SpreadsheetML tables (Open XML SDK)

Answer 2

to get all tables in the docx file you can use code below :

using System;
using Independentsoft.Office;
using Independentsoft.Office.Word;
using Independentsoft.Office.Word.Tables;

namespace Sample
{
    class Program
    {
        static void Main(string[] args)
        {
            WordDocument doc = new WordDocument("c:\\test.docx");

            Table[] tables = doc.GetTables();

            foreach (Table table in tables)
            {
                //read data
            }

        }
    }
}

And to write them into an excel file you have to do this for each cell :

 app.Visible = false;
        workbooks = app.Workbooks;
        workbook =  workbooks.Add(XlWBATemplate.xlWBATWorksheet);
        sheets = workbook.Worksheets;
        worksheet = (_Worksheet)sheets.get_Item(1);
        excel(row, column, "value");
        workbook.Saved = true;
        workbook.SaveAs(output_file);
        app.UserControl = false;
        app.Quit();

and finally excel function is as below :

    public void excel(int row, int column, string value)
    {
        worksheet.Cells[row, column] = value;
    }

Also you can use CSV or HTML format to create an excel file. to do that simply create a file example.xlsx with this content for CSV comma delmiated :

col1,col2,col3,col4 \n

val1,val2,val3val4 \n

or in HTML format :

<table>
 <tr>
  <td>col1</td>
  <td>col2</td>
  <td>col3</td>
 </tr>
 <tr>
  <td>val1</td>
  <td>val2</td>
  <td>val3</td>
 </tr>
</table>
