Tool: DOCX Generate — Zelaxy Docs

Generate a Word (.docx) document directly inside your workflow — no external API required. Provide a title and body text; the tool returns the file as a base64 string that you can pass downstream to a file-save step, an email attachment, or an HTTP response.

Overview

Property	Value
Type	`docx_generate`
Category	Tool — Document Generation
Auth	None (runs server-side, no API key required)

Operations

Operation	Tool ID	Description
Generate DOCX	`docx_generate`	Converts a title and newline-separated body text into a Word document and returns it as a base64-encoded string

Configuration

Setting	Type	Required	Description
`title`	`string`	No	Heading placed at the top of the document (Heading 1 style) and used as the filename. Defaults to `document` if omitted.
`content`	`string`	Yes	Body text for the document. Each newline-separated line becomes a separate paragraph.

Outputs

Field	Type	Description
`base64`	`string`	Base64-encoded contents of the generated `.docx` file
`filename`	`string`	Suggested filename for the file (e.g. `My Report.docx`). Derived from `title`, or `document.docx` when no title is set.
`mimeType`	`string`	MIME type of the file: `application/vnd.openxmlformats-officedocument.wordprocessingml.document`

Example

[Starter] → [Document Generator: DOCX (Word)] → [Agent: email the report]

Set the Title to {{starter.reportTitle}} and the Content to {{agent.summary}} (output from an upstream Agent block that produced the text). The DOCX Generate block returns {{docxGenerate.base64}} — pass this to a Resend or Gmail block as an attachment payload together with {{docxGenerate.filename}} and {{docxGenerate.mimeType}} to deliver the file by email.

Tips

No API key needed — this tool runs entirely on the Zelaxy server using the docx library; there are no usage limits or credentials to manage.
Title doubles as filename — whatever you put in the title field becomes the suggested download name. Use a descriptive value like {{starter.clientName}} Proposal to produce clean filenames dynamically.
One line = one paragraph — the content field splits on newlines. To create multiple distinct paragraphs, make sure your upstream text already has newlines between sections (e.g. Agent output with \n\n between paragraphs).
Attaching the file — most email and storage blocks accept base64 file payloads. Pass {{docxGenerate.base64}} as the attachment content, {{docxGenerate.filename}} as the filename, and {{docxGenerate.mimeType}} as the content type.
Part of Document Generator — in the visual editor, docx_generate is the DOCX (Word) option inside the Document Generator block. The same block also offers PDF (pdf_generate) and PowerPoint (pptx_generate) formats if you need a different output type.
