What is the .XQT File Extension?

.XQT File Extension Description:

The spreadsheet program SuperCalc developed by the Sorcim Corporation (later on acquired by Computer Associates), developed the .xqt file extension. The usage of the file extension .xqt is in reference to the macro capabilities of the program, which is intended to automate commonly, repeated tasks and commands used within the program. The SuperCalc spreadsheet application, that creates the file extension .xqt, is a contemporary of VisiCalc, which is considered as one of the pioneers in spreadsheet programs.

The SuperCalc application, which is identified with the .xqt file extension, was originally bundled with the WordStar application that was deployed in the Osborne 1 portable machine, as a software package called CP/M. The introduction of the file extension .xqt is seen as an improvement of the older VisiCalc, because of its inherent functionality for iterative solution.

The SuperCalc spreadsheet was noted as the first program to implement the concept of iterative resolution of circular references, or the interdependence of the result based on other common cells. This feature, which was inherent in the file extension .xqt associated software, was not introduced by Microsoft Excel, until after more than ten years of its implementation by SuperCalc.

The macro feature attached to the file extension .xqt has been omnipresent in almost all standard spreadsheet applications, which were merely for the earlier parts were automation of paper worksheets. The .xqt file extension's enforcement proved that spreadsheet programs were not mere alternatives, but rather; are tools to improve the functionality of the worksheet, as well as the productivity of the user.

The SuperCalc program, which generates the file extension .xqt, was hosted under the PC-DOS, Apple II and subsequently, the MS Windows Operating System environment where it adopted the name CA-SuperCalc.

Spreadsheets were not part of the initial surge of microcomputers. For the early part of the computing industry, the work of spreadsheet applications were done by mainframes that took literally hours to accomplish, what could be achieved now in just minutes. With the appearance of VisiCalc, which targeted the Apple II system, many other similar programs were introduced including the .xqt file extension associated software SuperCalc. The foundations laid down by these earlier types of programs are still used to build spreadsheet applications today.
