# Uploading Reconciliation Data

> Upload transaction data from your sources through a guided wizard so the Matcher engine can pair them in the next reconciliation run.

Before a reconciliation run can match transactions, you need to upload transaction data from your sources. The **New Reconciliation** wizard guides you through selecting a context and uploading a file in two steps.

## Uploading data

***

<Steps>
  <Step>
    Go to the **Reconciliations** page and click the **New Reconciliation** button.
  </Step>

  <Step>
    The ingestion wizard opens. In **Step 1 — Context & Date Range**, select the reconciliation context you want to run and set the date range for the period being reconciled.
  </Step>

  <Step>
    In **Step 2 — Upload File**, select the data source and file format, then upload the transaction file.

    <Note>
      Supported formats are shown in the format dropdown. Make sure your file matches the expected structure for the selected source.
    </Note>
  </Step>

  <Step>
    Click **Upload** to submit the file. The wizard confirms when ingestion has started.
  </Step>
</Steps>

## Tracking ingestion status

***

After uploading, monitor the ingestion job status in the [Job History](/en/platform/lerian-console/matcher-console/operational-history) page.
