Work with files and data
You can give Modelyx files, whole folders, voice notes and links, and the agent works with them directly: it reads documents, analyzes spreadsheets, processes images, audio and video, and returns finished results. Large files are processed with code in the Cloud Sandbox, so Modelyx can handle data that would never fit into a plain AI chat.
Ways to attach files
Everything is added from the task input (composer) at the bottom of the chat.
- + → Attachments → Upload File or Image: pick one or more files from your computer.
- + → Attachments → Upload Folder: add a whole folder at once, for example a month of exports or a set of contracts.
- Drag and drop: drop files onto the chat.
- Paste: paste an image or file from your clipboard.
- Voice input: record a spoken request, up to 1 minute per recording.
- Links: paste a URL into your message. The agent can open and read the page.
Supported formats
| Type | Formats |
|---|---|
| Images | JPG, PNG, GIF, WebP |
| Documents | PDF, Word, Excel, PowerPoint, Markdown, plain text, CSV, JSON, code files |
| Audio | MP3, WAV, M4A, OGG, WebM |
| Video | Common video formats such as MP4, up to 500 MB |
In Agent mode, images, audio and video are always accepted, because the agent can process them with tools (for example, transcribe a recording or pull frames from a video).
How Modelyx handles large files
In Agent mode, files you upload are copied into the chat's Cloud Sandbox automatically. The agent filters, joins and calculates with code and brings back only the results, so math over large tables is exact, many files can be merged at once, and you spend far fewer credits than pasting raw data.
Chat mode has no sandbox. Use Agent mode for large spreadsheets, many files or calculations. See Modes: Agent, Chat and Plan.
Attach files from your Library
Files you already stored in Modelyx don't need uploading again. Click Library in the composer and choose from Files / Libraries to attach a file or a whole library; the agent can search and read them. Libraries suit documents you return to often, such as specs or policies. See Resources and Library.
Example requests
Here are 6 Excel exports from our Wildberries account for April to September. Merge them, calculate revenue and returns by SKU per month, and give me the result as an Excel file with a chart.
I uploaded a folder with 40 supplier contracts in PDF. Make a table with supplier name, contract end date, payment terms and penalty clauses, and export it as CSV.

Limits
- Files go into the sandbox only in Agent mode, up to 50 files per chat sync and 500 MB per file.
- Scanned documents are read with OCR on a best-effort basis, so check results from poor scans.
- Storage depends on your plan. All limits are in Limits and supported formats.
