How can we get a Clean and Proper formatted HTML or PDF resume?

You can enable Formatted PDF HTML to improve the readability of HTML output for PDF resumes.
Use the following API settings:
"htmlresume": true,
"formattedpdfhtml": true
This setting attempts to provide a better-formatted HTML version of the original PDF resume. However:

It may take slightly more processing time compared to simple plain-text–based HTML.
Minor overlapping or layout inconsistencies may still occur, especially in complex or highly designed PDF resumes.
The output is not recommended for structured data mapping or ATS ingestion.

For consistent, fully structured, and branded HTML/PDF output, using Resume Templater is the recommended approach.

Hope this helps, but If have any questions pertaining to the API settings, please contact the RChilli support team. Just raise a query at RChilli HelpDesk or send an email at support@rchilli.com.
