Filler is for making data.

Use it to fill test databases, HTML tables, CSV documents, anything!

It makes sensible looking data in a variety of formats quickly and painlessly. From random strings and UUIDs to names and email addresses, Filler can generate millions of rows of data before you've made yourself a coffee.

Filler is iCloud-enabled, so your documents are available on all of your Macs. It looks great on Retina displays too.
