Download of ArrayMaker 2.1 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software lies within Developer Tools, more precisely Webmaster Tools. This free Mac app is an intellectual property of Thomas Grantham. We recommend checking the downloaded files with any free antivirus.
From the developer:
Array Maker is designed to help you convert large CSV files into arrays simply and easily. Therefore, with this tool you can turn a row of data in a spreadsheet into an array with ease. The app works with large amounts of data. This way, you can take out the mediocre drone work and spend that time perfecting your program.
You may want to check out more software for Mac, such as AcidSearch Installer, solr or joomla-, which might be similar to ArrayMaker.
