We have work to do until the end of 2027! The two most important milestones are "version 1" and "version 2".
Version 1 focuses on the engine's core functionality and performance while version 2 aims to produce a fully-featured spreadsheet application that can substitute existing solutions.
Note that IronCalc is the work of a very small team and, for now, a side project. Deadlines and priorities are subject to change. If you have a specific need or request, we encourage you to reach out.
The full engine
Arrays and array formulas are vital components of any spreadsheet engine. Dynamic arrays—a recent innovation from Microsoft Excel—are implemented by very few engines, yet they offer tremendous utility.
The engine and Web application will support three different languages (English, German and French) and a variety of locales. These settings affect how dates, times, currencies, numbers, and other region-specific formats are displayed. They also determine the default language used for functions and the user interface.
Although IronCalc already supports a good number of functions, we aim to support all of them.
The ready-to-use
product
Visual formatting to cells based on their values, making it easier to identify trends, outliers, and important data at a glance.
Organize data into structured tables with built-in sorting and filtering capabilities for better data management and analysis.
Provide rich interaction with cells. Easy navigation to external resources, other spreadsheets, or web pages. Interactive forms and standardized data entry with checkboxes and dropdowns.
Adding contextual notes and explanations to cells will help provide additional information without cluttering the main data.
To improve layout presentation and readability and compatibility.
Adding various chart types (e.g., bar, line, pie) to visualize and understand data. Charts make spreadsheets beautiful.
Enable real-time collaboration where multiple users can work on the same spreadsheet simultaneously with live updates and conflict resolution (CRDTs).
In https://app.ironcalc.com we intend to provide a user-friendly web application that allows users to create, edit, collaborate and share spreadsheets seamlessly. It will include a polished user interface, intuitive navigation, and a responsive design for various devices. For free, no ads, no intent to monetize it.
Beyond v2
Long-term vision
Native desktop applications for Windows, macOS, and Linux, providing offline access and system integration.
Create dynamic pivot tables to summarize, analyze, and explore large datasets with interactive filtering and grouping capabilities.
AI could help automate data analysis, generate insights, and assist with complex calculations and decision-making processes.
Allow users to write custom scripts and functions directly within the spreadsheet, enhancing flexibility and functionality.
We'll keep adding features and improvements as we go. IronCalc is open source, so if you have ideas you can contribute to it too!
