 > ⚠️ For each custom pointer key in each row, a server request is triggered to resolve the custom pointer key. For example, if the browser shows a class with 50 rows and each row contains 3 custom pointer keys, a total of 150 separate server requests are triggered.
 
-### CSV Export
+### Data Export
 
 ▶️ *Core > Browser > Export*
 
 This feature will take either selected rows or all rows of an individual class and saves them to a CSV file, which is then downloaded. CSV headers are added to the top of the file matching the column names.
 
 > ⚠️ There is currently a 10,000 row limit when exporting all data. If more than 10,000 rows are present in the class, the CSV file will only contain 10,000 rows.
 
+### Data Import
+
+▶️ *Core > Browser > Data > Import*
+
+Import data into a class from a JSON or CSV file. The file format is the same as the export format, so you can export data from one class and import it into another.
+
+- **JSON** — An array of objects, e.g. `[{ "name": "Alice", "score": 100 }, ...]`. Typed fields such as `Pointer`, `Date`, `GeoPoint`, and `File` are expected in Parse `_toFullJSON()` format.
+- **CSV** — Comma-separated with a header row. Column types are reconstructed from the class schema.
+
+The import dialog provides the following options:
+
+| Option | Description |
+|---|---|
+| Preserve object IDs | Use `objectId` values from the file instead of generating new ones. Requires the server option `allowCustomObjectId`. |
+| Preserve timestamps | Use `createdAt` / `updatedAt` from the file. Requires a `maintenanceKey` to be configured. |
+| Duplicate handling | When preserving object IDs: overwrite, skip, or fail on duplicates. |
+| Unknown columns | Auto-create new columns, ignore them, or fail on unknown columns. |
+| Continue on errors | Skip failing rows and continue, or stop on the first error. |
+
+> ⚠️ Disabling *Preserve object IDs* means new object IDs are generated. Any `Pointer` or `Relation` fields that reference objects within the same import file will not resolve correctly.
+
 ## AI Agent
 
 The Parse Dashboard includes an AI agent that can help manage your Parse Server data through natural language commands. The agent can perform operations like creating classes, adding data, querying records, and more.
