Improved Spreadsheet Rendering

Overview

Harvey now includes a native viewer for CSV and Excel files in Assistant. This improves spreadsheet reliability, preserves formatting, and enables cell-level citations in responses.

The native CSV and Excel viewer provides several improvements:

• Faster processing — spreadsheet processing time is reduced by up to 60%
• More reliable uploads — near-100% success rates across file sizes
• Cell-level citations — references point directly to the specific spreadsheet cells used in responses
• Higher-fidelity previews — formatting, layout, and multi-sheet structure remain intact

Supported File Types

The following file types are supported:

• .csv
• .xlsx

How to Use Spreadsheet Files in Assistant

1. Open Assistant.
2. Upload a CSV or Excel file (.csv, .xlsx) using the file upload button.
3. Enter your prompt asking Harvey to analyze or summarize the spreadsheet.
4. Review the response, which may include cell-level citations referencing specific rows or columns.

Sample Use Cases
