One SDK for every document-generation workflow

Start where your project already is — an empty page, a template your business team maintains, or a file that needs to be updated and republished.

Create from scratch

Build pages, sections, paragraphs, worksheets, charts, tables, slides, and forms through a comprehensive object model. The libraries handle format-specific packaging, layout, and serialization.

Generate from a template

Keep document design in the hands of the business. Open an existing Word, Excel, or PowerPoint template, bind application data to placeholders or markers, and preserve its branding, styles, and layouts.

Update existing files

Open supported documents, replace or add content, combine files, and publish the result in the format your users need. Work with files and streams to fit web requests, background jobs, and batch pipelines.

Create production-ready PDFs

Turn application data into production ready PDFs for invoices, reports, forms, and business documents with text, images, tables, headers, footers, page numbers, barcodes, bookmarks, annotations, attachments, layers, and interactive forms.

Create PDF files using PDF 1.7 and PDF 2.0 standards for broad compatibility.
Produce archival PDF/A variants and accessible, tagged PDF/UA output.
Protect sensitive output with encryption, permissions, and redaction.
Automate PDF forms and digital signatures with validation support.

Automate Word documents

Create richly formatted Word documents or automate business templates using a comprehensive document model with sections, paragraphs, tables, styles, headers, footers, fields, bookmarks, content controls, charts, shapes, and document properties.

Run advanced mail merge with arrays, business objects, ADO.NET data, dynamic objects, JSON, and XML.
Repeat nested regions for line items, schedules, catalogs, appendices, and other one-to-many data.
Protect generated documents with passwords, granular security access controls, and permissions.

Create and format text, images, shapes, tables, charts, SmartArt, hyperlinks, and sections.
Generate charts with an embedded data sheet so recipients can inspect and edit the underlying values.
Access and update placeholders, slide notes, animations, and transition effects.
