This plugin executed perfectly. Up to date php, woo and wordpress version as of 3/29/2023. I needed to add a meta_key to postmeta and update values. It detected all the users who already had the key and just updated the value. for those with out, it created the key and updated the value. The feedback on execution was perfect. Great job and many thanks. It saved me from having to develop the SQL commands which can be tricky.
