''Converting whole Open Food Facts "CSV" export to regular CSV''. Open Food Facts export use tabs as separator: it should be called TSV (tab separated values) instead of CSV (comma separated values). <code>csvkit</code> can convert TSV file into CSV very easily:
<code>$ csvclean -t en.openfoodfacts.org.products.csv > myCSV.csv</code>
''Selecting 2 column''s. Selecting two or three columns can be useful for some usages. Extracting two columns produce a smaller CSV file which can be opened by common softwares such as Libre Office or Excel. The following command creates a CSV file (brands.csv) containing two columns from Open Food Facts (code and brands). (It generally takes more than 2 minutes, depending on your computer.)
