> **loadStrings()** and BufferedWriter or using the Table class?

Well, **loadTable()** automatically parses CSV & TSV files for us:

> **[loadTable() / Reference](https://processing.org/reference/loadTable_.html)**
>
> Reads the contents of a file or URL and creates a Table object with its values. If a file is specified, it must be located in the sketch's "data" folder. The filename parameter can also be a URL to a …

And by using the Table class we have access to useful methods such as **getRowCount()**:

> **[getRowCount() / Reference](https://processing.org/reference/Table_getRowCount_.html)**
>
> Returns the total number of rows in a Table.

So you can find out the Table w/ the least number of rows.

Then afterwards, invoke **setRowCount()** on all 400+ Table containers, so they’ll all have the same number of rows:  
[Processing.GitHub.io/processing-javadocs/core/processing/data/Table.html#setRowCount-int-](http://Processing.GitHub.io/processing-javadocs/core/processing/data/Table.html#setRowCount-int-)

And finally, use **saveTable()** on each trimmed down Table:

> **[saveTable() / Reference](https://processing.org/reference/saveTable_.html)**
>
> Writes the contents of a Table object to a file. By default, this file is saved to the sketch's folder. This folder is opened by selecting "Show Sketch Folder" from the "Sketch" menu. Alter…
