Hello, I am converting an ebook from HTML to AZW3 using the command line (as part of a larger batch script) with the calibre converter. I can insert "standard" metadata into the AZW3 file as shown below with the "authors" field:
Code:
ebook-convert book.html %booktitle%.azw3 --authors %bookauthor%
I would like to insert metadata that goes into a calibre custom column: #words.
I checked Calibre manual (
https://manual.calibre-ebook.com/conversion.html) but could not find a solution.
Is it possible to automatically save custom metadata during conversion from the command line?
