title: Convert csv files,text files,pdf files into json using Azure Data Factory
body: <p>I have a scenario in which I'm pulling files from different sources, The files are in text,csv,json and pdf format. I'm pulling these files by using copy data activity of ADF. Now, the files should be loaded into cosmos db into the same table. I'm able to load the JSON files in cosmos db but other files format cannot feed into cosmos db. so I'm trying to convert other files into JSON but no help. I have gone through custom activity solution but due to some restriction I'm not able to complete the solution.</p>
  
  <p>Please let me know is there any way to transform text,csv,pdf files into JSON and can be feed into cosmos db.</p>
