# Create data catalogs

> Create a data catalog from a CSV file or by entering columns manually.

You can create a data catalog in two ways:

* **From a CSV file** — Upload the CSV and Vantage verifies the file name and data. If no catalog with the same name exists, a new one is created; otherwise Vantage updates the existing catalog.
* **Manually** — Create columns and data types by hand.

## Create a data catalog from a CSV file

<Steps>
  <Step title="Prepare your CSV file">
    Review these guidelines:

    * The imported CSV can't exceed 100 MB.
    * Columns must be separated by commas.
    * No spaces are allowed between a column name and its comma separator.
    * Values containing commas that should be treated as literals must be enclosed in double quotation marks.
    * Quotation marks inside string values must be duplicated. The entire string value must also be wrapped in double quotation marks.

    <Note>
      For sample CSV file fragments, see [Update data catalogs](/vantage/documentation/skill-designer/document/using-data-catalogs/update).
    </Note>
  </Step>

  <Step title="Upload the file">
    On the **Data Catalogs** tab, drag the CSV onto the page, or click **Browse** at the top of the screen to select it.
  </Step>

  <Step title="Set the catalog name and description">
    If needed, modify the data catalog name and enter a description.
  </Step>

  <Step title="Continue">
    Click **Next**.
  </Step>

  <Step title="Assign data types">
    Specify a data type for each column.
  </Step>

  <Step title="Create">
    Click **Create**.
  </Step>
</Steps>

A confirmation message appears; you can close it safely. The new data catalog appears in the list immediately, and the record count updates as Vantage finishes importing the CSV.

<Note>
  Large uploads may take time before the catalog is ready for use.
</Note>

## Create a data catalog manually

<Steps>
  <Step title="Open the create dialog">
    In the pane above the data catalog list, click **Create Catalog**.
  </Step>

  <Step title="Name the catalog">
    Enter a name and (optionally) a description.
  </Step>

  <Step title="Select a catalog type">
    Choose a type from the options described below.
  </Step>

  <Step title="Continue">
    Click **Next**.
  </Step>

  <Step title="Add columns">
    Click **Add Column** to create columns. Set each column's name and data type. To reorder a column, drag it by its left edge. To delete a column, hover over it and click **Delete**.

    <Note>
      For **Document Issuer Companies** and **Document Receiver Companies** catalog types, you can't reorder, edit properties of, or delete the predefined columns.
    </Note>
  </Step>

  <Step title="Create the catalog">
    Click **Create**. The new data catalog appears in the list.
  </Step>
</Steps>

### Catalog types

| Catalog type                    | When to use                                                      |
| :------------------------------ | :--------------------------------------------------------------- |
| **User-defined**                | Empty catalog, no predefined columns. Use for non-standard sets. |
| **Document Issuer Companies**   | Company searches — predefined columns (see below).               |
| **Document Receiver Companies** | Company searches — predefined columns (see below).               |
