RTF merge and make DOCx/Pages.

No.

Niel's approach is doable, though with testing, only plain text results from a copy/paste into Pages from Quick Look.

If you have a great deal of RTF formatted text, then you would need to open each individual RTF document in Apple's TextEdit and then copy/paste the formatted content, appending it to the open (and saved) Pages document.

Yes.

If your RTF documents are named numerically ascending (e.g. doc01.rtf, doc02.rtf, ... docnn.rtf) then one could automate appending them in that order directly to a Word .doc or .docx document. This is done in the folder containing these files from the Terminal command:

textutil -cat docx -output combined.docx *.rtf

or

textutil -cat docx -font Times -fontsize 12 -output combined.docx *.rtf

This will use the natural UNIX collating sequence to append the RTF files in their file naming order. The bad news, the Word document is still plain text.

Tested: macOS Tahoe 26.2, Pages v14.4

Select one in the Finder, press the space bar, and drag the document's text into the desired application. Some formatting may be lost.
