so possibly empty files are not allowed?
need minimum a table structure to make a header line
[https://editor.p5js.org/kll/sketches/Ie48wONx](https://editor.p5js.org/kll/sketches/Ie48wONx)
* * *
but usually start the other way, from reading a file
-a- create in online editor a subdirectory
/assets/
-b- create inthere a new file ‘Memory.csv’
edit it manually with 2 lines minimum,
one header line
one data line
(or upload the file from you computer )
and in your code just use
[https://p5js.org/reference/#/p5/loadTable](https://p5js.org/reference/#/p5/loadTable)
```auto
function preload() {
table = loadTable('assets/Memory.csv', 'csv', 'header');
}
```

Hello,
I used this example:
[https://p5js.org/reference/#/p5/saveTable](https://p5js.org/reference/#/p5/saveTable)
I edited it:
```auto
let table;
function setup() {
table = new p5.Table();
// table.addColumn('id');
//table.addColumn('species');
//table.addColumn('name');
//let newRow = table.addRow();
// newRow.setNum('id', table.getRowCount() - 1);
//newRow.setString('species', 'Panthera leo');
// newRow.setString('name', 'Lion');
// To save, un-comment next line then click 'run'
saveTable(table, 'new.csv');
}
// Saves the following to a file called 'new.csv':
// id,species,name
// 0,Panthera leo,Lion
```
It saves a csv file.
This works as well:
```auto
saveTable(table, 'new', 'csv');
```
Google Chrome was used along with [https://editor.p5js.org/](https://editor.p5js.org/)

My table is not empty I am entering valus as follows ::
tablo = new p5.Table();
tablo.addColumn(‘search\_key’);
tablo.addColumn(‘counter’);
```
newRow = tablo.addRow();
newRow.setString('search_key', key_search + "\t");
newRow.setNum('counter', counter);
```

The strange thing is when I saved the table using :
saveTable(tablo,‘Memory’,‘csv’); I’ve got the error msg
but if I save with:
saveTable(tablo,‘Memory’,‘html’);
the save is saved perfectly !
This strange behaviour is the reason of this post

so, you see that you got 2 answers what all say:
```auto
saveTable(table, 'filename.csv', 'csv');
```
or
```auto
saveTable(table, 'filename.csv');
```
works,
using the online editor,
( i give you already the link to my test code)
but again minimal test what works:
```auto
let table = new p5.Table();
function setup() {
saveTable(table,'Memory','csv');
}
```
and in my case using win 10 / firefox browser
* * *
why you not just give us the link to your
project in the online editor so we can reproduce that error.

I finally found the error : the p5.js library file was corrupted !
Now everything is working fine
Thanks to all of you

I posted [these examples](https://discourse.processing.org/t/savetable-with-p5/17475/3) along with this [reference](https://p5js.org/reference/#/p5/saveTable):
```auto
saveTable(table, 'new.csv');
Or:
saveTable(table, 'new', 'csv');
Will save a table as:
new.csv
```
```auto
And adding this:
saveTable(table, 'new.csv', 'csv');
```
So there are 3 ways to save the table to:
`new.csv`
