Google Now Offers Complete Client-Side Encryption for Google Sheets Data

Google has recently made a significant update to its Google Workspace suite, enhancing data confidentiality within Google Sheets. This upgrade, which brings full interoperability with Microsoft Office formats, is a direct response to the growing demand for stricter data governance and compliance in the enterprise sector.

The rollout began on September 4, 2025, for Rapid Release domains and will commence on September 18, 2025, for Scheduled Release domains. The schedule includes a staggered release for full visibility, ensuring a smooth transition for all users.

One of the key benefits of this upgrade is that it gives organizations direct control over encryption keys in Google Sheets. By placing encryption keys in the hands of the client, Google empowers organizations to meet rigorous industry standards. This feature is particularly beneficial for protecting sensitive data, such as financial data, personally identifiable information (PII), and other confidential business intelligence stored in spreadsheets.

The content of a file is encrypted in the user's browser before being stored in Google's cloud storage, providing an extra layer of security. Users can work with encrypted Excel files using Office editing mode and perform client-side conversions of Google Sheets to the Excel format.

Google has provided dedicated tools to facilitate this new feature. These include a data export tool for Vault, a decrypter tool for offline file access, and a converter tool to change exported Google Sheets files into Microsoft Office formats. Users can also import, export, and decrypt client-side encrypted files directly within Sheets.

The upgrade to Client-Side Encryption for Google Sheets was initially available by default for organizations that had already set up Client-Side Encryption. Specifically, this included Enterprise Plus, Education Standard and Plus, and Frontline Plus customers. The feature can be managed at the organizational unit (OU) level, allowing for flexible control.

This enhancement addresses critical compliance and data portability needs for enterprise customers, solidifying Google's commitment to providing secure, enterprise-grade collaboration tools. The integration with Google Vault and Takeout allows for the secure export of encrypted files, further ensuring data security.

End-users can convert an existing spreadsheet into an encrypted file by using the 'Make a Copy' option and selecting encryption. This move is a testament to Google's dedication to prioritizing data security and meeting the needs of its enterprise customers.
