What problem does it solve? Building a genuinely fillable Word form requires more than typing underscores on a page: it needs structured SDT content controls, legacy FormField checkboxes, MERGEFIELD placeholders, and document protection so only the intended fields are editable. Doing this by hand in OpenXML is error-prone, and most document tools cannot create these field types at all. ## Core Features & Use Cases - Structured form fields via OfficeCLI: Add text, richtext, dropdown, combobox, date, picture, and group SDT content controls with alias, tag, items, format, and lock properties, plus legacy FormField checkboxes (the only real checkbox type supported). - Mail-merge and protection: Insert MERGEFIELD, REF, SEQ, and IF complex fields for template-time data merge, then enforce protection=forms so end users can only fill fields while the rest of the document stays locked. - Use Case: An HR team needs an employee onboarding intake form where new hires type their name, pick a start date from a date picker, select a department from a dropdown, and tick a policy-agreement checkbox, while all legal text remains read-only. ## Quick Start Ask the AI to create a fillable employee onboarding intake form in Word with a full-name text field, a start-date picker, a department dropdown, an agreement checkbox, and forms protection enabled.
