SlackBackupAsHtml is a free Chrome add-on developed by tomomori. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory. The main purpose of this program is to output Slack search results as HTML files, making it a useful tool for backing up Slack messages.

With SlackBackupAsHtml, users can easily export their search results from Slack and save them as HTML files. This add-on was originally named SlackSearchToCSV, but it has been renamed to reflect its new functionality of only supporting HTML output. It is important to note that this program does not have the ability to export search results as CSV files anymore.

If you encounter an issue where clicking the RUN button of this extension on the Slack search results page does not display anything, try reloading the tab.
