Azure OpenAI Assistant API: How to Read All Tables from an Uploaded Excel File?

Hi everyone,

I'm working with the Azure OpenAI Assistant API's code interpreter feature. I uploaded an Excel file that contains three separate tables (each on a different worksheet/in different ranges). However, when I ask the assistant to read the Excel file, it only processes the first table and ignores the others.

Question:

  • Why does the assistant only read the first table?

How can I get the assistant to read and process all tables from the Excel file?

Additional Details:

I'm uploading the Excel file using the chat UI.

I want to extract and analyze data from all the tables within the file, not just the first one.

Any guidance or workaround would be greatly appreciated!

Thanks in advance!Hi everyone,

    Harinath J hi,

    by default, the assistant's code interpreter might just grab the first worksheet like a lazy reader skipping to chapter one and calling it a day. but we can make it read EVERYTHING.

    first, u gotta explicitly tell the assistant to loop through all sheets. try asking it something like 'can u read all worksheets from the excel file i uploaded? i need data from every single table, not just the first one!' sometimes being super clear helps ))

    if that does not work, u might need to get a bit more technical. the assistant can run python code in the background, so u can ask it to use pandas (a super handy data tool) to extract everything. something like "use pandas to read all sheets from my excel file. here's an example: import pandas as pd; xls = pd.ExcelFile('uploaded_file.xlsx'); all_sheets = {sheet: xls.parse(sheet) for sheet in xls.sheet_names}"

    now it should grab every worksheet like a hungry data monster ))

    for the official docs on how the code interpreter works, check out microsoft's guide on assistants. they explain how file processing happens, but yeah, sometimes u gotta tweak the approach.

    also, if ur tables are in defined ranges (not just whole sheets), u might need to specify those too. like "hey, in sheet 'Sales', my table is in range A1:D20 can u grab that specifically?"

    hope this helps! and hey, thanks for bringing this up, these little quirks are how we all learn together

    chheers,

    Alex
