Generic Excel Template Filler

Generic Excel Template Filler is a Dify tool plugin for inspecting and filling arbitrary Excel templates while preserving workbook formatting.

This universal version does not bundle domain-specific templates. Templates must be supplied by URL or as base64-encoded .xlsx content.

Features

• Inspect workbook structure, visible sheets, merged ranges, named ranges, placeholders, and non-empty cell previews.
• Fill values by explicit cell references such as Sheet1!B4.
• Fill named ranges discovered from the workbook.
• Replace text placeholders such as {{title}}.
• Optionally fill repeated issue rows when the template defines matching named ranges.
• Return the generated .xlsx file directly as a Dify blob, or upload it to a user-provided service and return a download URL.

Template Sources

Source	Description
url	Downloads an accessible .xlsx template from template_url.
base64	Decodes a base64-encoded .xlsx template from template_base64.

Recommended Workflow

1. Provide a template URL or base64 string.
2. Run inspect_excel_template to discover sheets, named ranges, and placeholders.
3. Prepare payload_json from the inspection result.
4. Run fill_excel_template to generate the final workbook.
5. Use delivery_mode=blob for direct file output, or delivery_mode=upload_link with provider upload credentials.

Payload Example

{
  "cells": {
    "Sheet1!B2": "Project Alpha",
    "Sheet1!B3": "2026-06-02"
  },
  "named_cells": {
    "customer_name": "Acme Inc."
  },
  "placeholders": {
    "{{title}}": "Monthly Report"
  },
  "output_filename": "monthly_report"
}

Privacy

The plugin processes templates and payload data in the Dify plugin runtime. It downloads a remote template only when template_source_type=url is selected and template_url is provided.
