Hi @Priya Jha ,
Thanks for your query and using this forum.
Unfortunately ADF doesn't have any out of box feature to read HTML file. One possible way is to use Custom Activity to transform/process data in a way that isn't supported by Data Factory, you can create a Custom activity with your own data movement or transformation logic and use the activity in a pipeline.
If it is a table content from an HTML webpage, then you can use Web table connector.
I would recommend you to please submit your feedback in ADF user voice channel: https://feedback.azure.com/forums/270578-azure-data-factory
