How to Bulk-Edit App Store Metadata Across Locales

Updated August 31, 2026 · by Sardorbek Rakhimov

Ten locales times name, subtitle, keywords, description, promotional text, and What's New is sixty values. In Apple's documented web flow, you select a language, edit that locale's fields, and save it before moving to another language. Once a listing is properly localized, every release turns into a bulk-editing problem. There are four honest ways to handle it; they trade setup cost against safety in different places.

Four ways to manage the same work

Workflow	Batch and review model	Setup and best fit
App Store Connect website	Edit and save one selected localization at a time; current Apple record, but no cross-locale comparison grid.	No setup. Best for a small number of edits and Apple workflows that remain web-only.
fastlane `deliver`	Upload locale-organized files; refresh with `download_metadata`; review with git diffs and deliver's HTML preview.	CLI, configuration, and source-of-truth discipline. Best for teams already using fastlane or CI.
Custom API scripts	Build exactly the read, validate, compare, and write flow you need against API resources Apple exposes.	Highest engineering and maintenance cost. Best for a genuinely custom or repeatable pipeline.
Native client	Product-dependent visual workflow; check whether it refreshes remote data, supports the needed fields, and stages a reviewable diff.	Install and authenticate. Best when visual cross-locale review matters more than script ownership.

Option 1: The App Store Connect website

For one or two locales, Apple's web UI is often enough: it needs no local setup and shows the App Store Connect record directly. At larger locale counts, each language is still a separate edit-and-save step, and there is no built-in side-by-side grid for checking consistency across every localization. Apple also makes editability field- and status-dependent, so a field that can be changed today may be locked during another version state. Agreements, tax, and banking continue through Apple's documented web workflows, as covered in the desktop client guide.

Option 2: fastlane deliver

fastlane's deliver action treats metadata as files: a metadata/<locale>/ folder per language with name.txt, keywords.txt, description.txt, and other supported fields. deliver init can seed those files from App Store Connect, deliver download_metadata can refresh them, and deliver uploads the local metadata. The wins are real: the files can live in git, version control provides diffs, deliver generates an HTML preview unless you bypass it with force, and its precheck applies a configurable set of community-maintained metadata checks.

The honest cost is synchronization discipline, not an inherent one-way limitation. Deliver can download metadata, but your local files can still be stale if someone edits App Store Connect after the last refresh. Its review is file- and HTML-based rather than an interactive cross-locale grid. It fits teams already living in fastlane and can be more setup than a solo developer wants for a one-off keywords pass.

Option 3: Custom App Store Connect API scripts

Apple's official App Store Connect API exposes specific resources rather than every App Store Connect web surface. For example, App Store Version Localizations covers version-specific descriptions, keywords, URLs, promotional text, and What's New; App Info Localizations covers fields such as name, subtitle, and privacy-policy URL. A custom client can combine those reads and writes into bulk find-and-replace or custom validation. You also own JWT authentication, pagination, conflict and error handling, rate-limit handling, editable-state rules, and changes to Apple's resources. It is worth that cost for a genuinely custom pipeline; it is usually heavy for occasional manual editing.

Option 4: A native desktop client

A native App Store Connect client aims at the gap the other three leave: cross-locale review and edit in one surface, without maintaining your own script. Capabilities vary by product, so verify that the client supports the fields you need, refreshes the relevant App Store Connect data, shows locales side by side, and — the safety property worth insisting on — stages changes and shows a diff before a bulk write reaches Apple.

Safety rules for any bulk edit

Read before write. Pull the current remote state first; never assume your local copy is current.
Review a diff, not a promise. Whatever the tool, see old-vs-new per field per locale before applying.
One field type per pass. A keywords pass, then a description pass — mixed passes make mistakes invisible.
Respect editable states. Metadata is only editable when the app status allows it; mid-review edits are how submissions get tangled.
Never blind-translate keywords. Bulk tools make it one click to machine-translate 100-character fields into nonsense — keywords are queries, not copy.

Where ShipZen fits

ShipZen is option 4 and is currently in public beta on TestFlight. Its published workflow includes a native cross-locale metadata editor using your own API key, a locale health scanner, and staged, diff-gated metadata writes, including supported AI-drafted changes. The security and capability page documents where credentials live and which actions remain outside ShipZen. The editor and scanner are free; applying a generated change set across every locale in one pass is a Pro feature. Current plans are listed in pricing.

Sources and verification (2026-08-31). Workflow and field-state claims were checked against Apple's localization instructions, editable-properties reference, App Store Connect workflow, and current App Store Connect API documentation. fastlane behavior was checked against the current deliver documentation and precheck documentation. ShipZen-specific statements describe the current public beta and link to its published capability boundary above.
