Excel Upload size limit increase

Venice models appear to have severe limitations on upload of excel files in terms of the amount of text. I have a large spreadsheet with 20k rows I'd like to upload but all the models I've tried say it is too large by 14-20x amount of text. I get this error even with Gemini, Claude and ChatGPT models selected. But I am able to upload this excel file on ChatGPT, Gemini and Claude directly. Please can we get an increase to the uploaded file text size limit?
