What is SpreadSheetSpace?


SpreadSheetSpace allows MS Excel spreadsheets to maintain synchronization with other MS Excel spreadsheets and with external Software Platforms (e.g., ERP, CRM, etc.) to support collaboration and real time data analysis.

Synchronization takes place under strict security guarantees. No more data delocalization in untrusted servers, as Cloud service providers offer to monetize your data. With SpreadSheetSpace, synchronization relies on strong end-to-end asymmetric encryption and data never leaves the user administrative domains unencrypted.


Sync supports real time/historical data analysis from within MS Excel. Software Platforms expose internal tables to MS Excel users, who incorporate them in their spreadsheets to create local analyses and reports. SpreadSheetSpace maintains the spreadsheets permanently in sync.

No more periodic table extraction from Software Platforms! SpreadSheetSpace keeps the user spreadsheets aligned to the latest table version. In addition, it also maintains the history of the table versions to support business evolution analysis.


CO-EDIT allows people to edit spreadsheets jointly. SpreadSheetSpace CO-EDIT is based on the absence of data delocalization in untrusted Cloud servers, which guarantees full security thanks to strong end-to-end encryption, and on controlled access to shared tables.

No more conflicts due to simultaneous editing of the same tables! SpreadSheetSpace greatly facilitates teamwork while guaranteeing strong security.

Confidentiality first!


SpreadSheetSpace uses an asymmetric cryptography mechanism based on RSA algorithm.

User's key pair is generated automatically and in a totally random context during installation process, the private key will never leave user's computer in any case. The SpreadSheetSpace server will only be aware of the public keys that will be used to encrypt the data.

No one will be able to read encrypted data except recipient users using their own private keys.
