ACF Pro stores repeater data as a count plus underscore-prefixed sub-field keys in wp_postmeta, so a single landing page with a ten-row feature list writes more than thirty meta rows under names like features_0_title, features_0_icon, and _features_0_title. Flexible-content layouts follow the same pattern with a layout string per row, and gallery fields store comma-separated attachment IDs. The post edit screen renders these field types cleanly one record at a time, but auditing a hundred landing pages for missing feature icons becomes a scripting exercise.

SleekView reads ACF Pro's registered field groups and pivots repeater rows into proper child tables, one row per features_{n}_* bundle. Each sub-field becomes a sortable column, the parent post stays linked, and edits go through update_sub_field() so acf/save_post and field-level hooks fire as expected. Flexible-content layouts get a layout-name filter so you can isolate every page using a particular block. Gallery fields expand to one row per attachment with the attachment's title and mime type joined in.

The same mechanism covers ACF on terms, users, and options, which is where ACF Pro Extensions add-ons usually plug in. Inline edits fall back to a direct meta write only when the field has no ACF update path, and SleekView records a conflict for review if two editors touch the same sub-field at once. Nothing is moved out of the meta tables; the audit layer just finally matches the shape of the data.

ACF Pro is the most common rich-content modeling layer on WordPress, and its repeater and flexible-content fields are the reason teams reach for it instead of plain custom fields. The cost of that flexibility is shape: repeater rows live as serialized counts plus dozens of underscore-prefixed sub-field keys in wp_postmeta, all linked back to the parent post by row index. The post edit screen handles this beautifully one record at a time, but ten landing pages with ten repeater rows each is a hundred sub-field bundles to audit, and the default admin gives you no cross-post view of any of them.

Editors open every post to verify a single feature title, developers write one-off WP_Query helpers for each schema migration, and bulk operations fall back to WP-CLI. SleekView reads the registered field definitions and pivots the repeater rows into proper child records, one row per sub-field bundle, with the parent post linked and the sub-fields shown as columns. Filters work on sub-field values, inline edits route through update_sub_field(), and flex-content layouts get a layout-name filter for fast cross-post audits.

The serialized storage stays where ACF put it, and the admin finally matches the shape of the content.
