The paid version of Gemini – Gemini Advanced – now allows you to upload files to perform data analysis. You can upload multiple files on Gemini Advanced and ask questions from the documents. The best part is that you can throw multiple files in different formats on Gemini at once and ask questions related to them. So I tested Gemini's file upload feature and compared it to ChatGPT. Here are my findings.

You can upload different file types like PDF, CSV, DOCX, XLS, XLSX, TXT, DOTX, RTF and TSV on Gemini. This basically means you can upload PDF files, Office files like Word documents, Excel spreadsheets, CSV files and more. There is also support for JPG, JPEG, PNG and WEBP image files, but these are also available on the free version of Gemini.

Additionally, you can connect your Google Drive via Gemini Extensions and upload Spreadsheets and Documents as well.

Compared to ChatGPT, however, file support is limited on Gemini. ChatGPT can process any type of file you feed to the chatbot. From ZIP files to coding languages like JSON, PY, XML; data files such as SQL and MATLAB; audio files such as WAV and several other file formats are supported by ChatGPT.
