### Selecting the file for import

In this part of the process, you will upload a file from your device.

1. Go to <img src="/api/docs/image/54176ad07f146575310749eba44b7c2f42c1b327/icons/data-modeling-hub-icon.svg" alt="Data Modeling Hub icon" class="icon"> **Data Modeling Hub > Imports > New import**.
2. As the data type for import, select **Voucher pool**.
3. As the import method, select one of the following options:
    - Import a local file - To import a single `.csv` file to Synerise.
    - Import in Automation - To import a .`csv`, `.json`, `.jsonl`, and `.xml` files and execute periodical imports.


      <div class="content-tabs" data-tab-group="tabgrp-1268">
      <div class="tab-buttons"><button class="tab-button" data-tab-id="tabgrp-1268-0" data-tab-group="tabgrp-1268" data-tab-active="true">Local File</button><button class="tab-button" data-tab-id="tabgrp-1268-1" data-tab-group="tabgrp-1268">Automation</button></div>

      <div class="tab-panel" data-tab-id="tabgrp-1268-0" data-tab-group="tabgrp-1268" data-tab-active="true">

      1. Upload the `.csv` file by using the **+ Upload file or drop one here** field.
      2. Optionally, you can customize the file metacharacters by clicking the arrow down icon.
          1. From the **Delimiter** dropdown, select the character that marks the end of a column.
          2. From the **Quotation mark** dropdown list, select the characters that contain the text or data type.
          3. From the **Escape character** dropdown lists, select the character which changes the default interpretation of a character or a string followed by the escape character.
      3. To proceed to the next step, click the **Next** button.

      ### Selecting voucher pool

      Select the voucher pool to which you want to import your data. If you selected the Import option on the interface of a specific voucher pool (**Data Modeling Hub > Voucher pools**), the voucher pool will be selected automatically.

      ### Selecting column with codes

      You can import only codes into the voucher pool. Your file must contain a column with the codes. However, if your file contains more than one column, at this stage you must indicate which column contains the codes. 

      The remaining columns will not be imported.

      ### Launching import

      After selecting the column that contains a code, you will be redirected to the mapping summary. If it's correct, to launch the import, click **Run import**.

      <div class="tab-panel" data-tab-id="tabgrp-1268-1" data-tab-group="tabgrp-1268">

      1. Select the method of delivering the file:
          - Local File - This option allows you to upload a file from your device.
          - SFTP protocol - This option allows you to upload a file from a server using the SFTP protocol.
          - HTTPS protocol - This option allows you to upload a file from a server using the HTTPS protocol.  
          - Amazon S3 - This option allows you to upload a file from Amazon S3 bucket.
          - Azure - This option allows you to upload a file from Azure Blob Storage.
          - Google Cloud Storage - This option allows you to upload a file from Google Cloud Storage.
      2. Click **Go to import template**.  
      3. Define the settings of the [Scheduled Run node](/docs/automation/triggers/scheduled-run).
      4. Depending on the method of delivering the file, configure the settings of [Local File](/docs/automation/integration/http-integrations/http-get-file) or the [Get File](/docs/automation/integration/http-integrations/http-get-file) node that uses HTTP protocol or the [Get File](/docs/automation/integration/sftp-integrations/sftp-get-file) node that uses SFTP protocol. 
      5. If the data requires modification, configure the settings of the [Data Transformation node](/docs/automation/operation/data-transformation-node). If you have prepared the transformation rules for the data structure of the imported file, select it from the dropdown list. If not, create it from scratch.  
          You can remove this node if your data doesn't require transformation.
      6. The rest of the nodes in the default template don't require any further configuration.
      7. If your workflow is ready, click **Save & Run**.
