What is “Mashmatrix Sheet” ?

Mashmatrix Sheet is a web application that allows you to view and edit data on Salesforce as if it were an Excel sheet-like interface.

Until now, when maintaining the data on Salesforce, it was necessary to export it by CSV etc. and edit it on Excel, then import it again or use the data loader etc. to import it into Salesforce .

With Mashmatrix Sheet, you can perform data maintenance on the browser as it is after logging in to Salesforce without having to do cumbersome data export work. We provide familiar Excel-like interfaces and operations such as filtering and sorting. Mass editing of multiple records by copy & paste are also possible.

The created sheet can also be shared by users in the Salesforce organization, so it is possible for multiple people to smoothly perform tasks requiring data entry.

Since all applications run on the Salesforce platform, there is no need to worry about data leakage to the outside.
