Hello I am new to Processing. I want to parse a csv file but it does not get it.  
Can you help me please?  
Thanks  
My code is 🙂

```auto
Table table;

void setup() {
  
  table = loadTable("C:/Users/Seyfi/Desktop/processing-3.5.3/mammals.csv", "header, csv");

  println(table.getRowCount() + " total rows in table"); 

  for (TableRow row : table.rows()) {
    
    int id = row.getInt("id");
    String species = row.getString("species");
    String name = row.getString("name");
    
    println(name + " (" + species + ") has an ID of " + id);
  }
  
}

```

the processing way is to make under the sketch dir  
a subdir /data/ where you have files like

- fonts
- image
- data
- saved image/ pdf/ files( string / csv / json ) …  
so please start with

```auto
String infile = "data/mammals.csv", outfile = "data/backup.csv";
table = loadTable(infile, "header, csv");

```

only this way you keep your data with the project and are mostly independent from OS the project is run from later.

* * *

also the install directory  
processing-3.5.3  
is a bad place for user data.

possibly you have a other problem,  
where is your sketch directory?  
/ File / Preferences /  
Sketchbook location:  
???

> C:\Users\Seyfi\Desktop\processing-3.5.3\modes\java\application

This is where the sketch file is under. Is it fine?

no, i would call that a system directory  
for the Processing 3.5.3

and also that that is under Desktop ( not totally bad, ) shows that you might not know how to handle disk and files under windows?

again, did you set that sketch path in the preferences?

> Processing IDE / File / Preferences / Sketchbook location:

a windows way would be

```auto
C:\Users\Seyfi\Documents\projects\processing\

```

( make the dirs projects\processing\ first )

later when you use

> Processing IDE / File / Sketchbook

that directory opens and show your sketches  
my\_sketch\_1 ( click for open )  
( contains: my\_sketch\_1/mysketch\_1.pde )

no, first save your code using  
/ File / Save As /  
so we can see that project in above directory

/TableS contains TableS.pde ?

down there you create /data/

> /TableS/data/

and copy csv file into

> /TableS/data/mammal.csv

* * *

and not forget to declare

```auto
String infile = "data/mammals.csv";

```
