2025-11-07 // Mark Tressler

A data room is a secure, online platform where sensitive data is stored and shared. Data rooms are often used to share spreadsheets and documents during due diligence and audits but are increasingly being used to share sensitive data between partners, vendors, and clients.

Row Zero is a secure spreadsheet that can be used as a virtual data room to securely share sensitive data. In this guide, we’ll show how Row Zero’s advanced security, big data power, and cloud connectivity make it easy to create spreadsheet data rooms that can auto-update and support massive datasets.

What is a data room?

A data room (sometimes called a virtual data room or VDR) is a secure online platform where sensitive information is stored and shared. Virtual data rooms are designed so that specific individuals can securely review sensitive information, but cannot download, share, or duplicate the information they see.

Data rooms are often used during fundraising, M&A, audits, and for sharing sensitive data with partners or clients.

Using Row Zero as a secure spreadsheet data room

Row Zero is a secure cloud spreadsheet that can be used as a dynamic data room for large datasets. Row Zero works like Excel and Google Sheets, but offers several key features that make it a powerful data room solution:

Advanced cloud security

  • Granular access controls - Set access controls by data source, spreadsheet, and user. Row Zero spreadsheets can also inherit row level security (RLS) and role-based access controls (RBAC) from the data warehouse.
  • Restrict downloads, sharing, copy/paste - Organizations can choose to restrict all data export and duplication, including copy and paste.
  • PrivateLink - Organizations can connect spreadsheets to their data warehouse via PrivateLink so that data never transits the internet.
  • Dedicated data plan - Data is never co-mingled.
  • Region lock - Data can be locked in a specific geographic region so that organizations can enforce data residency.
  • Compliance controls - Row Zero is SOC 2, GDPR, and HIPAA compliant.

Connected and auto-updating

Row Zero has built-in, secure connectors to data warehouses like Snowflake, Databricks, Redshift, etc. that make it easy to build connected spreadsheets that auto-update.

Big data power

Row Zero is the world's most powerful spreadsheet and is specifically designed to handle massive datasets. Enterprise plans can support billion row spreadsheets, which is 1000x bigger than Excel's limit of 1,048,576 rows.

Workspaces

Workspaces are a security feature that allow admins to isolate sensitive data from other workspaces in an organization. Workspaces have their own membership, spreadsheets, data sources, and security settings. Workspaces let organizations have multiple, separate data rooms within Row Zero.

Data room use cases in Row Zero

Row Zero's unique features support a wide range of data room use cases that are not well supported by typical data room solutions:

  • Dynamic data rooms that auto-update - Row Zero's secure data connectors let you build connected spreadsheets that auto-update and securely share them with specific users. This can be particularly useful for sharing sensitive, updating data between partners.
  • Data rooms for very large datasets - Row Zero supports massive datasets well beyond the limits of Excel and Google Sheets. You can also upload and view very large files including big CSVs, parquet, JSONL, txt, etc.
  • Multi-room data rooms - Row Zero's workspaces feature lets you set up multiple data rooms within the same organization. This can be useful for creating separate data rooms for separate clients, investors, or other stakeholders.
  • Low cost data room - Row Zero can be used as an affordable data room solution for any size company, from startups to large enterprises, and costs significantly less than popular data room solutions. View pricing.

Conclusion

Row Zero is a secure spreadsheet that can be used as a virtual data room for sensitive spreadsheet data. Row Zero spreadsheets offer advanced security features common in data room solutions like granular access controls, activity tracking, and the ability to restrict data export, sharing, and duplication.
