My spreadsheet application
zSpeadsheet is my very frugal Qt-based application that is quite responsive even on resourced-contrained computers like the Raspberry Pi 4.
zSpreadsheet is essentially my Linux port of my iOS app of the same name, to which it is functionally equivalent.
It supports the following files types:
- Its native .isp file format
- CSV (comma separated value) and TSV (tab separated value) files
- Export to HTML
- Export to RTF
- Export to Excel 2003
zSpreadsheet has support for HiDPI e.g. Retina displays.
I wrote the Linux port in C++ and I built the GUI using the Qt 5 user interface library, whereas the iOS app I wrote in Objective-C using UIKit.
While I ported zSpreadsheet to run mainly on Linux systems, both Qt and C++ are platform-agnostic so it could in theory run on Windows, MacOS, Haiku OS, etc.
I don't intend it to be as sophisticated as something like LibreOffice, but rather it is a product of my philosophy of frugality and simplicity in computing.
