How to create documents online from a template?

Question

Documentation

Good afternoon! The essence of the task: you need to implement the creation of a document in the browser, according to a template in which you can edit certain fields, and insert images into certain fields that would be automatically formatted. As a result, we get a well-marked document with a company logo, regalia, etc. with the ability to export to PDF and XLS or DOC. Are there any ready-made solutions or frameworks where to dig?

Answer 1

Did you try to do this with the usual Google Docs?
