A set of React components lets you embed viewers for PDF, DOCX, XLSX and CSV files straight into your app. Each viewer supports bounding-box citations—so you can highlight passages or table cells and link back to specific spots in a document. Uploading files, signing PDFs electronically and downloading edited versions all come built in. Since it’s open source, you get full control over styling and behavior. Drop these components into customer dashboards, chatbots that need to reference reports or your own admin tools without wiring up a custom parser. The code handles rendering and interaction, so you avoid building viewers from scratch or wrestling with browser quirks.
