# Defining a component schema to read a delimited file

Defining the component schema of your delimited file helps you parse the data you are working with.

## Before you begin

You must have added and configured a tFileInputDelimited component (see [Configuring a component to read a delimited file](https://help.qlik.com/talend/en-US/sorting-a-file-talend-studio/8.0/Configuring%20a%20component%20to%20read%20a%20delimited%20filehttps://help.talend.com/en-US/reading-a-file-talend-studio/8.0/configuring-a-component-csv)).

## Procedure

1. In the Designer, double-click the tFileInputDelimited component.
2. Click the […] button next to Edit schema.

   The Schema wizard opens.
3. Click the plus button to add a Column.
   1. Add as many columns as there are headers in your .csv file.

      Information noteNote: Headers are the first values in a .csv file. ![](https://help.qlik.com/talend/en-US/sorting-a-file-talend-studio/Resources/images/csv_header.png)
   2. Enter the name of each Column.

      Column names must be identical to header names.
      ## Example
      * First
      * Last
      * Number
      * Street
      * City
      * State
   3. Select the Type of each Column.

      Information noteTip: Select the String Type for a postcode. A postcode number does not serve an arithmetic function.
4. Click OK.

## Results

You have defined the schema of your file.
