Attaching files
Use the paperclip button in the composer, or drag files onto it. The analyst can read the attachment alongside your question, which is useful for a broker note, an export, or a screenshot. Accepted file types:
Each file can be up to 20 MB. Legacy binary
.doc files are not supported; save as .docx first. Files upload as soon as you add them; sending waits until uploads finish.
Working with data attachments
The analyst does more than read a CSV, TSV, or Excel file as text. It has a notebook that opens the file, runs calculations, and filters or reshapes the data before answering. It’s the same kind of work you’d do in a spreadsheet, just driven by your question instead of formulas.In this holdings export, which positions are above 5% of the portfolio?

If the holdings are your own, you can skip the export entirely: connect your brokerage and the analyst works from your actual positions and weights, no file required.
