From April 13th, 2020 to January 20th, 2022, 50% user give 5-star rating, 50% user give 4-star rating. for Copy as Plain Text - Format Cleaner chrome extension.
Best extension of this type I could find because it keeps formatting such as carriage returns etc so that the text is still organized after pasting. Others remove this leaving giant blocks of text you have to sift through to recreate the paragraph structures etc. 4 star because I'd like to see the copy as plain text option be immediately accessible in the context menu rather than in a sub-menu. Maybe make this an option in extension settings?
Very very underrated. It doesn't even need to run in the background to do it's job. So it literally uses zero RAM while among other extensions for the same purpose, the lowest RAM consumption was 16MB.
