Reindexing data from the backend in Magento 2 is only possible with a dedicated extension, as the native Magento 2 admin panel has limited reindex capabilities. Using the Magento 2 Backend Reindex Extension, here is how to reindex data from the backend:

• Go to System → Index Management in your Magento 2 admin.
• View the status of all available indexes — such as Product Price, Catalog Search, Inventory, and Category Products.
• Select one, multiple, or all indexes.
• Hit Reindex Data to trigger the process immediately.
• Monitor the index status as it updates to Ready in real time.

The Magento 2 Reindex from Admin Panel feature ensures your store data stays accurate and current without touching the server.
