# Import a CSV

> Bring a spreadsheet into Oneprofile as a new table, with column names and types you can adjust before adding the rows.

Oneprofile can build a new table straight from a CSV file. Upload it, check the columns Oneprofile matched, adjust anything that looks wrong, then add the rows.

## Bring in your file

<Steps>
  <Step title="Open the Import a CSV card">
    On the **Tables** page, choose the **Import a CSV** card. Its description reads "Bring a spreadsheet in as a new table." This opens the **Import a CSV** dialog.
  </Step>

  <Step title="Add your file">
    Drag a CSV onto the dialog, or click to choose one from your computer. Oneprofile treats the first row of the file as the column names, and files must be under 50MB. While it reads the file, the dialog shows **Reading the file…**.
  </Step>

  <Step title="Review the column mapping">
    Oneprofile shows a table with **Column name**, **Type**, and **Sample values** for every column it found, with a type already guessed for each, such as **Text**, **Number**, **Date**, or **Email**.

    Edit a column's name directly in its field, or change its type from the dropdown if the guess is wrong. Untick a column's checkbox to leave it out. Unticked columns are not added to the table.
  </Step>

  <Step title="Check the sample values">
    The mapping table only shows the start of a few values per column. Click the expand icon next to a column ("See all sample values") to open a dialog titled **Sample values for "…"**, with the column's name in place of the ellipsis. It lists every sampled value with its row number, and names how many rows of the file it's showing. Click **Close** when you're done.
  </Step>

  <Step title="Name the table and set how many rows to add">
    Set the **Table name** field. Oneprofile suggests the file's name to start, and asks for one if you clear it. The **Rows to import** field is seeded with the whole file. Lower it to add only some of the rows.
  </Step>

  <Step title="Create the table">
    Click **Create table**. It stays disabled until every included column has a name and no two share one, for example "Every included column needs a name."
  </Step>
</Steps>

<Note>
  If a file has more rows than your plan holds in one table, Oneprofile names both the file's size and how many rows fit, and adds only the rows up to that limit. An **Upgrade** chip next to the message takes you to raise it.
</Note>

<Tip>
  A column can look empty in the mapping table just because its first values are blank. Open its sample values before you trust the type Oneprofile guessed.
</Tip>

## After you create the table

Oneprofile takes you straight to the new table. Adding the rows runs in the background as a run, so you can start working, such as adding a column, before it finishes.
