Document generation for Oracle APEX

Word templates in, PDFs out.

Renduva fills Word templates with your data and returns PDF or DOCX, from one line of PL/SQL. It runs on your own server, so business data never leaves your network.

Simple document generation, on your own servers

The parts an APEX application needs, and nothing it doesn't.

Templates made in Word

Design invoices, letters and certificates in Word. Type {{field}} where data goes, repeat table rows for each line, and swap stand-in pictures for logos and photos. Everything else prints exactly as designed.

Many records, one PDF

Send one record or a thousand. Each is filled from the same template and merged, in order, into a single PDF: a whole bill run in one call.

Built for PL/SQL

A small PL/SQL package returns the document as a BLOB, from APEX pages, plain PL/SQL and scheduler jobs. Build the JSON in SQL, get the PDF back.

Runs on your servers

One container or one RPM inside your network. Your data never goes to a cloud service, and nothing calls home, so it also works off the internet.

Keys, not data, in the logs

Every call needs an API key; only key hashes are stored. Logs record status and timing, never templates or the data in them.

Any language

One HTTP endpoint. Anything that can send JSON (Python, Java, C#, Node.js, Go) gets the same documents as PL/SQL.

How it works

Design in Word

Write the document as usual and type tags where the data goes: {{customer}}, and {{#items}} … {{/items}} around a table row.

Call it

From PL/SQL, renduva.generate('invoice', l_json). From anything else, one POST /generate with the same JSON.

Get the document

The filled document comes back as a PDF (via LibreOffice) or DOCX: to store, email, or download from an APEX page.

Small on purpose

Renduva does one job well: Word templates to PDF and DOCX, called from the database.

If you need spreadsheets, slide decks and dozens of formats, larger reporting tools exist. If you need invoices, statements, letters and certificates from APEX, generated inside your own network, at a price a small team can approve, Renduva is the short route: one server, one PL/SQL package, a template language you can learn in five minutes.
