Thank you for your inquiry. Could you please elaborate a bit more about the formats of input documents? In general, you can transform all your input documents in a single format and then merge/concatenate all those files in a specific arrangement. It depends upon the input file formats.
All the documents are Microsoft Word documents. We have to sort based on the Merge field parameter value in each document. Please let me know for further details. Thanks
You can Join or Append Documents using Aspose.Words. Regarding 'sort based on the merge field parameter value', can you please elaborate how are you passing merge field value? Are you using mail merge for this purpose of some other code?
