Create a local file upload source connector in the UI

This tutorial provides steps for creating a local file upload source connector to ingest local files to Platform using the user interface.

Getting started

This tutorial requires a working understanding of the following components of Platform:

Upload local files to Platform

In the Platform UI, select Sources from the left navigation bar to access the Sources workspace. The Catalog screen displays a variety of sources for which you can create an account.

You can select the appropriate category from the catalog on the left-hand side of your screen. Alternatively, you can find the specific source you wish to work with using the search option.

Under the Local system category, select Local file upload, and then select Configure.


Use an existing dataset

The Dataflow detail page allows you to select whether you want to ingest your CSV data into an existing dataset or a new dataset.

To ingest your CSV data into an existing dataset, select Existing dataset. You can either retrieve an existing dataset using the Advanced search option or by scrolling through the list of existing datasets in the dropdown menu.


With a dataset selected, provide a name for your dataflow and an optional description.

During this process, you can also enable Error diagnostics and Partial ingestion. Error diagnostics enables detailed error message generation for any erroneous records that occur in your dataflow, while Partial ingestion allows you to ingest data containing errors, up to a certain threshold that you manually define. See the partial batch ingestion overview for more information.


Use a new dataset

To ingest your CSV data into a new dataset, select New dataset and then provide an output dataset name and an optional description. Next, select a schema to map to using the Advanced search option or by scrolling through the list of existing schemas in the dropdown menu.


With a schema selected, provide a name for your dataflow and an optional description, and then apply the Error diagnostics and Partial ingestion settings you want for your dataflow. When finished, select Next.

Select data

The Select data step appears, providing you an interface to upload your local files and preview their structure and contents. Select Choose files to upload a CSV file from your local system. Alternatively, you can drag and drop the CSV file you want to upload into the Drag and drop files panel.


Only CSV files are currently supported by local file upload. The maximum file size for each file is 1 GB.


Once your file is uploaded, the preview interface updates to display the contents and structure of the file.


Depending on your file, you can select a column delimiter such as tabs, commas, pipes, or a custom column delimiter for your source data. Select the Delimiter dropdown arrow and then select the appropriate delimiter from the menu.

When finished, select Next.



The Mapping step appears, providing you with an interface to map the source fields from your source schema to their appropriate target XDM fields in the target schema.


Preview data

Select Preview data to see mapping results of up to 100 rows of sample data from the selected dataset.


During the preview, the identity column is prioritized as the first field, as it is the key information necessary when validating mapping results. When finished, select Close.


Add calculated field

Calculated fields allow for values to be created based on the attributes in the input schema. These values can then be assigned to attributes in the target schema and be provided a name and description to allow for easier reference.

Select the Add calculated field button to proceed.


The Create calculated field panel appears. The left dialog box contains the fields, functions, and operators supported in calculated fields. Select one of the tabs to start adding functions, fields, or operators to the expression editor.


Tab Description
Function The functions tab lists the functions available to transform the data. To learn more about the functions you can use within calculated fields, please read the guide on using Data Prep (Mapper) functions.
Field The fields tab lists fields and attributes available in the source schema.
Operator The operators tab lists the operators that are available to transform the data.

Select the expression editor to manually add fields, functions, and operators. Once you have created a calculated field, select Save to proceed.


Filter source schema mapping tree

To filter through your source schema, select All source fields and then select the specific field that you want to map from the dropdown menu.

The following table displays the sorting options for your source schema tree:

Source fields Description
All source fields This option displays all of the source fields of your source schema. This option is displayed by default.
Required fields This option filters the source schema to only display the fields required to complete the mapping.
Identity fields This option filters the source schema to only display the fields marked for Identity.
Mapped fields This option filters the source schema to only display the fields that have already been mapped.
Unmapped fields This option filters the source schema to only display the fields that have yet to be mapped.
Fields with recommendation This option filters the source schema to only display the fields that contain mapping recommendations.


Intelligent recommendations

Platform automatically provides intelligent recommendations for auto-mapped fields based on the target schema or dataset that you selected. You can manually adjust mapping rules to suit your use cases.


To accept all the auto-generating mapping values, select Accept all target fields.


Sometimes, more than one recommendation is available for the source schema. When this happens, the mapping card displays the most prominent recommendation, followed by a blue circle that contains the number of additional recommendations available. Selecting the light bulb icon will show a list of the additional recommendations. You can choose one of the alternate recommendations by selecting the checkbox next to the recommendation you want to map to instead.


Alternatively, you can choose to manually map your source schema to your target schema. To do this, hover over the source schema you want to map, then select the plus (+) icon.


The Map source to target field popover appears. From here, you can select which field you want to be mapped, followed by Save to add your new mapping.


When finished, select Finished.


Monitor data ingestion

Once your CSV file is mapped and created, you can monitor the data that is being ingested through it using the monitoring dashboard. For more information, see the tutorial on monitoring sources dataflows in the UI.

Next steps

By following this tutorial, you have successfully mapped a flat CSV file to an XDM schema and ingested it into Platform. This data can now be used by downstream Platform services such as Real-time Customer Profile. See the overview for Real-time Customer Profile for more information.
