Step 1: Create a New Meta Box Fields Import

Navigate to All Import › New Import and provide a valid import file. Select the post type with the attached Meta Box custom fields from the dropdown menu.

In this example, we're importing Meta Box custom fields to Properties.

Next, click Continue to Step 2.

Step 2: Review the Import Data

The Review Import File screen appears, which lets you validate the import file and its data:

Besides reviewing the records to import, you can also apply filters by expanding the Manage Filtering Options section.

Click on Continue to Step 3.

Step 3: Map Incoming Data to Meta Box Custom Fields

You now see the Drag & Drop screen, which lets you map the import data elements into the respective target fields.

To map a data element, drag it from the right panel and drop it on the matching field on the left:

The Meta Box Add-On section is the place to define your Meta Box custom fields. Search for that section:

Enable the field groups where you want to import Meta Box custom fields and map each field as needed. Here are some examples:

Once you've finished mapping all the Meta Box custom fields, click Continue to Step 4 (not shown) at the bottom.

Step 4: Define Import Settings

Next up is the Import Settings screen, where most import settings can be defined:

This interface lets you assign or generate a Unique Identifier to be used in the import. To generate one automatically, click on Auto-detect. To create the identifier manually, use drag and drop.

Midway down the screen, you can control other import options, such as how the import will behave if it runs again and whether it creates, updates, or removes records.

There are also sections for Scheduling Options and other Configure Advanced Settings. We'll leave those alone for now and click Continue.

Step 5: Run the Import and Check Your Meta Box Fields

The Confirm & Run screen appears, which includes an Import Summary section to review everything that will happen when you run the import.

To execute and run the import, click on Confirm & Run Import.

Once the import completes, you will see an Import Complete message:

You can then proceed to review the newly imported properties.

That's how you import Meta Box custom fields into WordPress using WP All Import!

Field Labels and Values

Meta Box lets you define both a value and a label for the choices inside the field definitions.

You can define those choices in a format such as value : Label.

For example, red : Red. This is how that looks in the Meta Box field setup:

Then, to import into those fields, you can use the values in the Set with XPath option. If you only have labels, then use those.

Create Custom Fields Groups in Meta Box

To create a new custom field group in Meta Box, do the following:

1. Go to Meta Box › Custom Fields and click Add New.
2. Input a title for the field group.
3. Under Settings, define where the fields are going to appear.
4. Under Fields, add your new fields, which you can do by clicking + Add Field and choosing the field to add.
5. Publish the new field group, and you're done!

You will see the new Meta Box custom fields when editing the chosen post type or when importing into it. Meta Box has more documentation about this here: How to Create Custom Fields?​.
