This page will instruct on how to automatically redact all spreadsheet objects. This article will assume that the basics of Blackout's Spreadsheet Projects are understood. Information on this can be found in the link below.
To redact specific objects on a spreadsheet check out the guide linked below.
First, navigate to the Blackout tab. Then from there to the Spreadsheet Projects sub-tab. Using a new or existing project go to the rules page. There will be a checkbox with the text "Redact all Excel Objects" next to it which you can see in the image below.
Once the box was checked and when the job has been run all excel objects (barring charts which are done through text redactions) will be redacted.
To learn about the other settings found in our screenshot check out our Mass Redacting Headers and Footers in Excel.
