Improved Spreadsheet Rendering

What’s New

Harvey now includes a native viewer for CSV and Excel files in Assistant.

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

Why It Matters

This improves spreadsheet reliability, preserves formatting, and enables cell-level citations in responses.

How to Use

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

Identify Inconsistencies

Upload a spreadsheet alongside supporting documents and ask, “Identify any inconsistencies between this spreadsheet and the uploaded contract.”

Summarize Spreadsheet Data

Upload a spreadsheet and ask, “Summarize the key trends in this spreadsheet.”
