CSV & JSON convertor tool

This is a full-featured CSV parsing tool running entirely on your brower. No data leave your computer ! Use it also to learn how to use our packages and to test the various options interactively.

DownloadButton is a simple component for letting the user download a javascript-generated file. It was extracted from Notablemind.

sed is stream editor, but can edit files directly too, with the following:

sed -i -e 's/foo/bar/g' filename

s is used to replace the found expression "foo" with "bar"

g stands for "global", meaning to do this for the whole line. If you leave off the g and "foo" appears twice on the same line, only the first "foo" is changed to "bar".

-i option is used to edit in place on filename.

-e option indicates a command to run.
