RANGA is described as 'is the must-have project planning tool used by planners to automate their routine tasks. RANGA bridges the world's largest spreadsheet software EXCEL and PRIMAVERA P6 the standard for Planning and Scheduling'. There are four alternatives to RANGA for Windows, Online / Web-based and Linux. The best alternative is Project Tracker. Other great apps like RANGA are ScheduleReader (Paid), Oracle Primavera (Paid) and XER Schedule Toolkit (Paid).
ScheduleReader displays well formatted and visually understandable schedule information, extracted from XER, XML and XLS project schedule files that can be easily customized and organized to meet the end user needs.
XER Schedule Toolkit converts data from complex planning software packages (such as Primavera P6, Asta Power Project, and Microsoft Project,) and enables you to view and analyse the information within the familiar surroundings of Microsoft Excel.
