+# Write to CSV
+
+## Single Address
+
+```python
+import geocoder
+import csv
+
+g = geocoder.bing('Avenida da Republica, Lisboa')
+
+with open('test.csv', 'wb') as f:
+    writer = csv.DictWriter(f, fieldnames=g.fieldnames)
+    writer.writeheader()
+    writer.writerow(g.json)
+```
+**Note**: The `fieldnames` is new in 1.1.3, `attributes` in the earlier versions.
+
+## Multiple Address
+
+The CSV file used for **locations.csv**.
+
+Using `delimiter` for parsing a CSV might include `<\t> <;> <|> <,>`
+
+
+| location    | extra      |
+|-------------|-----------|
+| Canada      | best      |
+| Australia   | amazing   |
+| Venezuela   | awesome   |
+
+```python
+import geocoder
+import csv
+
+rows = []
+fieldnames = ['location', 'extra', 'lat', 'lng', 'state', 'country']
+
+with open('locations.csv') as f:
+    reader = csv.DictReader(f, delimiter=';')
+    for line in reader:
+        g = geocoder.google(line['location'])
+
+        # Add the CSV line data into the Geocoder JSON result
+        result = g.json
+        result.update(line)
