Files API - uploading an excel

Hi everyone,

My question is regarding the Files API here https://platform.openai.com/docs/api-reference/files/create and more specifically with the “purpose=assistants” parameter. I can see that the Assistants API will be shut down in August as per the announcement in their page. https://platform.openai.com/docs/assistants/deep-dive

Does anyone know if this specific parameter will stop working as well after the deprecation? I could not find this information anywhere.
What I am trying to do is to upload an excel file and then use the code_interpreter tool via the Responses API to work over that excel file. Right now it seems only the “assistants” purpose can accept excel/csv files so wanted to check if there is any mention of this anywhere
