One API. Two capabilities.

Clean REST endpoints to generate, sign, and deliver documents.

01

Documents Generation

Documents Generation

Transform data into pixel-perfect PDFs, DOCX, XLSX, and PPTX — server-side, at any scale, from templates your team already knows. Templates in Word, Excel, PowerPoint, Google, Dynamic data binding and conditional logic, Sync and async generation modes, Reusable data sources and document pipelines.

Digital Signatures

Documents Generation

Transform data into pixel-perfect PDFs, DOCX, XLSX, and PPTX — server-side, at any scale, from templates your team already knows. Templates in Word, Excel, PowerPoint, Google, Dynamic data binding and conditional logic, Sync and async generation modes, Reusable data sources and document pipelines.

How it works

From API call to signed document.

Connect your data

Upload a JSON file or connect a live data source.

Upload your template

Word, Excel, PowerPoint, or Google formats — built with fields, expressions and elements.

Generate

One API call combines template and data into a finished document, sync or async.

Download the output

Retrieve the generated file, or have Doctavian deliver it straight to your own storage.

Ready to build?
