About project

This is the Excel project that was created using Pure JavaScript only.

The following basic features are implemented in this project:

1. SPA custom framework
2. pages routing
3. simple components rendering (without Virtual DOM or Shadow DOM)
4. global state storage object (like Redux)
5. global events emitter object for data transmission between components
6. using localStorage for state saving
7. custom library for DOM operations (like JQuery)

Some new features have been added by me:

1. new cells selection logic (using mouse)
2. highlighting the selection of a group of cells along the outer contour
3. add focus to the end of the line inside div contenteditable cells
4. unselect row and column headings during cells resizing
5. adding the ability to enter a formula in a cell
6. getting a formula of an active cell (or value when cell is inactive)
7. delete styles and data from a selected group of cells (using delete button)
