Delimited Text Plugin

The Delimited Text plugin allows you to load a delimited text file as a layer in QGIS.


To view a delimited text file as layer, the text file must contain:

  1. A delimited header row of field names. This must be the first line in the text file.
  2. The header row must contain an X and Y field. These fields can have any name.
  3. The x and y coordinates must be specified as a number. The coordinate system is not important.

As an example of a valid text file we import the elevation point data file elevp.csv coming with the QGIS sample dataset (See Section~label_sampledata):


Some items of note about the text file are:

  1. The example text file uses ; as delimiter. Any character can be used to delimit the fields.
  2. The first row is the header row. It contains the fields X, Y and ELEV.
  3. No quotes (") are used to delimit text fields.
  4. The x coordinates are contained in the X field.
  5. The y coordinates are contained in the Y field.
Using the Plugin

To use the plugin you must first enable it as described in Section sec:managing_plugins.

Click the new toolbar icon Delimited text.png Add Delimited Text Layer to open the Delimited Text dialog as shown in Figure 42.

First select the file (e.g., qgis_sample_data/csv/elevp.csv) to import by clicking on the Browse button. Once the file is selected, the plugin attempts to parse the file using the last used delimiter, in this case a semi-colon (;). To properly parse the file, it is important to select the correct delimiter. To change the delimiter to tab use \t (this is a regular expression for the tab character). After changing the delimiter, click Parse.

Once you have parsed the file, choose the X and Y fields from the drop down lists and enter a Layer name (e.g., elevp ) as shown in Figure 42. To add the layer to the map, click Add Layer. The delimited text file now behaves as any other map layer in QGIS.
