What modifications can I make in the PDF editor?
At the level of changing text and design online like in docx documents?
I have attached a sample DOCX file
I use the merge field to insert data from the sql database
I would like to enter (by drag and drop if possible) the merge field directly from my web on the browser to the online PDF editor
And even making the data conversion operation online
It depends upon how Aspose.Words converts merge fields while creating PDF (e.g. if merge fields are converted into form fields, then you can use Aspose.PDF to fill forms).
If merge fields are converted into plain text in PDF, then you can perform find/replace operation. Furthermore, please note that we don’t provide any online editor. Online Apps are just demonstration of how APIs can be used in the code behind to achieve the functionalities (also online apps do not demonstrate all of the APIs features).
Have a look at this documentation article for Aspose.PDF editor functionality. You can post your issues (or to get more details on back-end APIs) regarding Aspose back-end APIs here.
