“With ViewExport, we were able to easily work with a very large Slack export and resolve our incident much faster compared to other Slack export solutions. The tool has great functionality with improvements happening on a regular cadence as well as fantastic support from the ViewExport team.”
“Glad for ViewExport - in Slack you can't filter easily by date range, which is annoying and not usable for Legal/eDiscovery. And Onna is way too expensive. You guys are perfect.”
