About
SheetRender turns a spreadsheet into a stack of separate, print-ready PDFs. Upload your data (CSV, XLSX, or a Google Sheet) plus one example of a document you already use, like a certificate, invoice, or offer letter. It reads the layout and builds the template for you.
That's the difference. Other merge tools (Autocrat, Form Publisher, mail merge add-ons) make you rebuild your document as a template full of <<merge tags>>. With SheetRender you show it a finished example, check the field matching, fix anything in plain language, and generate. Each row becomes its own PDF, ready to download or send by email.
People use it for training certificates, HR offer letters, invoices and quotes, and personalized reports. Output is print-ready A4, Letter, Legal and more, with scheduled runs and email delivery built in. There's a free plan with no credit card required, and a set of free in-browser PDF tools (merge, split, extract pages) on the website.

About
Thinkfree Document Editor SDK, previously offered as Thinkfree Office, lets developers embed a full Office editor in web applications and control documents through object-level APIs. It supports Word, spreadsheet, and presentation editing for DOCX, XLSX, PPTX, and ODF files, without building an editing layer from scratch.
The SDK is designed to work as part of an application rather than as a separate Office product. Applications can combine interactive editing with programmatic document operations and AI workflows, allowing users to review and continue editing in the same editor.
• Embeddable Office editor UI for word processor, spreadsheet, and presentation documents
• 900+ Object-level APIs for paragraphs, tables, ranges, sheets, charts, slides, and shapes
• High-fidelity editing for DOCX, XLSX, PPTX, and ODF documents
• Document tools that LLMs or AI agents can invoke
• Real-time collaborative editing
• Self-hosted deployment, or a Thinkfree-managed cloud API
