Sound familiar?

Thousands of people fill the same documents by hand, every single day.

“We fill out 15 of these a day, 5-10 min each. This would be very important to me as a large portion of my job.”

— Microsoft Q&A user

Best answer they got: “Learn Microsoft Access.”

“I download the spreadsheet, delete headers, replace with tokens, link database, and merge. It is a pain in the rear.”

— Lawyer, JotForm Forum

“In 1990 I bought a program that did this. It is now 33 years later and this can't be done anymore?”

— ExcelDemy commenter

“I want to turn an existing Word document into a fillable template. Just like search and replace but with a wizard interface.”

— Experts Exchange

Stop doing this:

  • ✗Manually typing into blanks every single time
  • ✗Copy-pasting from old versions and missing fields
  • ✗Spending hours setting up Mail Merge templates
  • ✗Paying $90/mo for tools that still need merge tags
  • ✗Learning Microsoft Access just to fill out forms

Frequently asked questions

Does this work with PDF files?+
Yes! Magic Decoder supports both Word (.docx) and PDF files. Upload either format and AI will identify the fillable fields automatically.
Do I need to add merge tags or special formatting?+
No. That's the whole point. Upload the document exactly as you already have it — blanks, underscores, example data, whatever. AI figures out what the fields are.
How is this different from Mail Merge?+
Mail Merge requires you to set up a data source, insert merge fields with special syntax, and rebuild everything when someone edits the template. Magic Decoder requires zero setup — just upload and fill.
What about formatting? Will my document look the same?+
Magic Decoder preserves the structure and layout of your original document. Your completed document comes back formatted and ready to send.
Is my data secure?+
Your documents are processed securely and not stored permanently. We use encrypted connections and don't train AI models on your data.
Can I save a template and reuse it?+
Yes — save any parsed template to your Form Library and fill it again anytime without re-uploading. Parse once, fill forever.
