How to use it
  1. 1. Prepare your template

    Open any Word or OpenOffice document and mark every spot that should change with double curly braces, e.g. {{Name}}, {{Date}}, {{Course}}. Keep the layout and styling exactly as they are.

  2. 2. Upload it

    Drag your .docx or .odt file into Step 1 above, or click to choose it. The tool scans the file and finds every placeholder automatically - no manual setup needed.

  3. 3. Fill in the values

    Step 2 shows one input field for every placeholder found in your template. Type in the values you want.

  4. 4. Download

    Step 3 lets you download the finished document as a PDF or in the original .docx/.odt format, with every placeholder replaced by the value you entered.

Example

Say your template contains this line:

Certificate of completion for {{Name}} — Course: {{Course}} — Date: {{Date}}

You fill in:

  • {{Name}} → Jane Doe
  • {{Course}} → Web Development
  • {{Date}} → 18/09/2026

And the downloaded document reads:

Certificate of completion for Jane Doe — Course: Web Development — Date: 18/09/2026
