Maintain page numbers as it is in original docx when merging

[santhosha]

I am trying to merge multiple docx to a single docx . But in this process the page numbers get auto incremented.
I need to maintain the page numbers from the original docx such that no auto increment happens in the merged doc. I use Spire.Doc to merge the docx files.

Spire.doc version - 13.8.0

Hello,

Thank you for your inquiry.
To merge the files while preserving the original page numbers of the documents, please refer to the following code using the latest version of Spire.Doc for .NET 13.9.10:

Code: Select all

            Document document = new Document();
            document.LoadFromFile(@"Test1.docx");
            Document document1 = new Document();
            document1.LoadFromFile(@"Test2.docx");

            for (int i = document1.Sections.Count - 1; i >= 0; i--)
            {
                Section section = document1.Sections[i];
                document.Sections.Insert(0, section.Clone());
            }

            for (int i = 0; i < document.Sections.Count; i++)
            {
                Section section = document.Sections[i];
                HeaderFooter footer = section.HeadersFooters.Footer;
                if (footer.Paragraphs.Count <= 0) continue;
                Paragraph paragraph = footer.Paragraphs[0];
                foreach (DocumentObject documentObject in paragraph.ChildObjects)
                {
                    if (documentObject.DocumentObjectType == DocumentObjectType.Field)
                    {
                        Field field = (Field)documentObject;
                        if (field.Type == FieldType.FieldNumPages)
                        {
                            field.Type = FieldType.FieldSectionPages;
                        }
                    }
                }
                section.PageSetup.RestartPageNumbering = true;
                section.PageSetup.PageStartingNumber = 1;
            }

            document.SaveToFile(@"result.docx", FileFormat.Docx);

If the above code does not meet your requirements, please send us the files you used for testing, and we will conduct further investigation. You may upload the files as attachments or send them directly to my email: [email protected]. We look forward to your feedback.

Hi

Thank you for your response.

We use Spire.doc for Python. Please find the code snippet below for further reference.

Code: Select all


merged_doc = None

for root, dirs, files in os.walk(documents_path):
   for file in files:
      filename, extension = os.path.splitext(file)
      if extension in ['.docx','.doc']:
         doc_file_path = os.path.join(root,file)
         
         source_doc = Document()
         source_doc.LoadFromFile(doc_file_path)
         source_doc.KeepSameFormat = True


         if merged_doc is None:
            merged_doc = source_doc
         else:
            # merged_doc.ImportContent(source_doc)
            # # print(dir(merged_doc))


            for sec_content in range(source_doc.Sections.Count):
               section = source_doc.Sections.get_Item(sec_content)
               cloneSection = section.Clone()
               cloneSection.HeadersFooters.LinkToPrevious = False
               cloneSection.PageSetup.RestartPageNumbering = True
               cloneSection.PageSetup.PageStartingNumber = 1
               merged_doc.Sections.Add(cloneSection)
 

merged_doc.SaveToFile("MergeDocument.docx", FileFormat.Docx2019)
merged_doc.Close()
source_doc.Close()

The merging functionality is working fine now. However, we have encountered one more issue.

Consider two DOCX files:

The first document has 3 pages

The second document has 2 pages

When we merge these two documents, the page numbering in the merged output shows as 1 of 5, 2 of 5, and so on.
What we actually need is:

For the first document: 1 of 3, 2 of 3, 3 of 3

For the second document: 1 of 2, 2 of 2

In other words, each document’s page numbering should remain relative to its own total page count, not the combined total after merging.

Please let us know how we can achieve this using Spire.Doc for Python.

merged_doc.Close()

We tried the suggested solution, but unfortunately the page numbering still isn’t working as expected. Even after applying the section-based numbering logic, each merged document is showing a continuous total (e.g., 1 of 5) instead of restarting numbering per section (1 of 3, 1 of 2, etc.).

We’ve attached the two sample source files along with the merged output for your reference. Could you please review and let us know what might be causing this issue?

Hello,

Thank you for your feedback.
When I opened your result file, the output appeared as shown in the screenshot below. Could you please tell us whether you are seeing the same result in your environment?

To address this issue, I have adjusted the code accordingly. Please refer to the following code. In my local environment, the result file now displays as shown in the subsequent screenshot. I have also attached my result file for your reference.

Code: Select all

import os
from spire.doc import FileFormat, Document, DocumentObjectType, FieldType

merged_doc = None
for root, dirs, files in os.walk(R"...\test"):
    for file in files:
        filename, extension = os.path.splitext(file)
        if extension in ['.docx', '.doc']:
            doc_file_path = os.path.join(root, file)

            source_doc = Document()
            source_doc.LoadFromFile(doc_file_path)
            source_doc.KeepSameFormat = True

            allpages=0
            if merged_doc is None:
                merged_doc = source_doc
                allpages = merged_doc.GetPageCount()
                print(allpages)
            else:
                allpages = source_doc.GetPageCount()
                print(allpages)
                for i in range(source_doc.Sections.Count - 1, -1, -1):
                    section = source_doc.Sections.get_Item(i)
                    merged_doc.Sections.Insert(0, section.Clone())


for i in range(merged_doc.Sections.Count):
    section = merged_doc.Sections.get_Item(i)
    footer = section.HeadersFooters.Footer
    if footer is not None:
        footer.ChildObjects.Clear()
    section.PageSetup.RestartPageNumbering = True
    section.PageSetup.PageStartingNumber = 1
    footerParagraph = footer.AddParagraph()
    footerParagraph.AppendField("page number", FieldType.FieldPage)
    footerParagraph.AppendText("/")
    footerParagraph.AppendField("number of pages", FieldType.FieldSectionPages)

merged_doc.SaveToFile(R"testresult.docx", FileFormat.Docx)
merged_doc.Close()
