CsvLab

A simple, (mostly) command line interface app to view, edit and plot data in common csv files, designed to perform on-the-fly data visualization and manipulation when you have no time to turn a proper computer on.

Through the I/O button, you can access a menu allowing you to retrieve a CSV file from an url, to save the current table to a local csv (in the device's public folder), or load the file from such folder.
In the "settings" tab, you can choose graph position (if any) and the columns to be displayed as x and y for the plot.

Through text commands in the main tab, you can perform multiple operations, such as:
- Manually modifying values in the table by column name and row
- Filter rows by index or by the value of a string column
- Define new columns as the product of a mathematical operations between previous columns, and/or a column and a scalar
- Define new columns as differential, cumulated sum/product or ratio of elements of a pre-existing column
- Remove columns
- Evaluate basic statistic metrics on one/two columns.
