How to Merge More Than 25 DOCX Files in Microsoft Word
Question details
Users need a reliable method to combine a large number of Word documents into a single file without any being skipped.

- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Assembling many chapters or separate sections into one main comprehensive document.
- Observed behavior
- Microsoft Word skips documents and fails to include all files when inserting more than 25 DOCX files using the Insert > Object > Text from File feature.
Before merging your documents, place all the DOCX files into a single folder and prefix their file names with sequential numbers (e.g., 01_Chapter.docx, 02_Chapter.docx) to ensure they are inserted in the correct order.
Use Insert Text from File in Smaller Batches
The most reliable manual workaround for the file insertion limit is to combine your documents in manageable batches of 20 to 25 files at a time.
Since Microsoft Word can struggle with memory management when processing large quantities of files simultaneously, breaking the task into smaller chunks ensures no documents are skipped during the merge.
Launch Microsoft Word and create a new blank document to serve as your master file.
Navigate to the 'Insert' tab on the top ribbon. In the 'Text' group on the right side, click the small arrow next to 'Object' and select 'Text from File'.
In the file explorer window, navigate to your folder and select the first 20 to 25 documents. Click 'Insert' and wait for Word to process them.
Place your cursor at the very end of the newly inserted text, then repeat the 'Text from File' process for the next batch of 20-25 files until all documents are merged.

Automate the Merge with a VBA Macro
For users who frequently assemble large numbers of documents, using a VBA macro can bypass the manual batching process and automate the entire merge.

Frequently Asked Questions
Why does Word skip documents when I merge a large number of files?
Microsoft Word can struggle with memory management and temporary file generation limits when attempting to process more than 25 separate files simultaneously through the 'Text from File' feature. This causes the software to quietly skip some files without displaying an error message.
How can I ensure my files merge in the exact order I want?
When using the 'Text from File' feature, documents are typically inserted in alphanumeric order. To enforce the correct sequence, rename your files with leading numbers (such as 01_Chapter.docx, 02_Chapter.docx, 03_Chapter.docx) prior to starting the merge process.
Does merging multiple files preserve their original formatting?
By default, the inserted text usually adapts to the destination master document's style definitions. To keep your original formatting intact, ensure all source documents share the exact same template and style definitions as your master document before merging.
Can I merge PDF files along with DOCX files in Word?
Word will attempt to convert PDF files into DOCX format before inserting them, which can disrupt formatting or slow down the process significantly. For the best results, convert your PDFs to Word documents beforehand, or use a dedicated PDF merging tool to combine them.
