You can prepare your documents(DOCX,PDF,XLXS) by adding special text tags before uploading them. These tags define where and what kind of fillable fields—like Text, Signature, or Date—should appear.
Once the aforementioned document is uploaded to document placeholder and converted to PDF, these tags will automatically be turned into fillable fields. This helps streamline your workflow by letting you control the field setup directly in the document.
Tip: The font size of fillable fields added via fillable field tags is always 12.
For example, the fillable field tags being used for the ‘Text’ line are the following:
{{t:t;r:n; l:"TextField1";}} where:
t:t - the field type -Text
r:n; - required - yes/no (y/n)
l:"TextField1"; - field name
The fillable field tags first being used on the ‘Sign Here’ line are the following:
{{t:s;r:n;l:“SignatureField1;”}} where:
t:s- the field type - Signature
r:n; - required - yes/no (y/n)
l:"SignatureField1"; - field name
The table below shows the most widely used fillable field tags along with the types of fields for which these fillable field tags can be applied.
KEY | What does it mean? | Accepted format & values | What fields need this KEY? |
t | TYPE of the field | s (for signature) i (for initials) t (for text) d (for dropdown) c ( for checkboxes) dt or date ( for dates) | For every field |
r | REQUIRED | y (for required) n (for optional) | For every field |
