In their own words
Docxtemplater
Docxtemplater is a JavaScript library that generates Word, PowerPoint, Excel, and OpenDocument files by filling templates with JSON data. Users add tags such as {user} to a Word or PowerPoint template, and the engine replaces them with supplied values. The core library is open source under MIT/GPLv3 and includes basic templating; advanced features are available through paid modules sold individually, in a four-module PRO pack, or through ENTERPRISE. The library is tested with active Node.js versions 12 through 24 and common browsers. Its Docker API accepts a template and JSON data over HTTP and produces DOCX, PPTX, or XLSX files. The ENTERPRISE Docker image supports use from several programming languages, while code integration uses JavaScript with examples for common frameworks. Generation runs locally without outbound network requests; on-premise deployment and air-gapped environments are supported with the APPLIANCE license. Developers configure the library, while office users can create templates with their existing document skills. Paid plans start at €500 a year. Rendering DOCX page layout and page breaks is outside its scope.
Formstack Documents
Formstack Documents is a cloud, no-code document generation service that turns business data into dynamic files. Users can create templates with the AI-powered Document Builder or upload DOCX, PPTX, PDF and CSV templates. Data from CRMs, form builders, databases and other business systems populates those templates. Conditional logic can show or hide sections, while routing can combine files or generate multiple documents from one source. CRM data can produce proposals, contracts, invoices and reports. Bulk generation, data merging and an open REST API support larger workflows. Documents can be sent to Formstack Sign or DocuSign for electronic signatures. Listed protections include SSL, encryption, firewall protection, secure downloads and document encryption; Formstack says merged data is not stored. HIPAA and GDPR compliance are listed. The service runs on the web and through an API, with documentation and ticket support. A free trial is available, but there is no free plan.
