Dencho Rename, the Invoice Filename Machine
A browser-based Japanese tool that extracts details from invoice and receipt PDFs and renames them in bulk.
Field notes
The tool presents extracted fields in a review table before generating the renamed files, with controls for date format, separators, document labels, document numbers, company-name normalization, and preservation of the original filename. It supports text-based PDFs; scanned image PDFs require manual naming. The page also distinguishes foreign-currency documents, leaving the amount for the user to enter in yen, and offers ZIP download plus index-book CSV functionality through its plan structure.
