Changing the price or text of many Bookings services usually means opening each one. This app lists your services in one table and exports them to CSV for review and editing in a spreadsheet.
When you choose a CSV, or select services on the screen, the app shows a table of what would change before anything is written. In Pro, it can then apply the changes, 100 services at a time; failed rows show a reason. You can add text to names or descriptions, raise or lower fixed prices by an amount or a percentage, set appointment durations, turn online booking on or off, hide or show services, and assign existing categories. Before each apply, it saves a backup file you can load to restore.
Free shows the list, exports standard columns to CSV and shows the table of changes. Pro adds applying, all columns, Shift_JIS and JSON export, restore, and creating appointment services from a CSV (customer's location, with staff IDs). It works within one site, not across sites. Prices change on fixed-price services only.
It reads service settings: names, descriptions, categories, prices, durations and options. It does not read bookings, customers, contact details or payment records.
