Hello there, pals !

This is the first day of my #100DaysOfCode in Data Analytics. To be honest, I had no idea where to start with this challenge's tech stack. After that, I tweeted the same thing, and several aspiring data analysts advised me to start with Excel. As a result, I chose to begin with Microsoft Excel.

Excel , But why ?

Microsoft Excel is one of the most widely used data analysis programmes. They are without a doubt the most sought-after analytic tool accessible, as they come with built-in pivot tables. It's a one-stop data management solution that lets you import, examine, clean, analyse, and display your data with ease.

Here are a few things I've discovered:

Excel User Interface

Basic Formatting

Absolute vs Relative vs Mixed Cell Referencing

Cell Modes

Possible Data types

1. Excel User Interface

  • Ribbon tabs
  • Name box
  • Formula bar
  • Columns
  • Cells
  • Rows
  • Ribbon groups
  • Ribbon controls
  • Sheet tabs
  • Split controls - Horizontal & Vertical
  • Status bar
  • Quick access toolbar
  • Title bar

2. Basic formatting

Shortcut keyDescription
CTRL + BApplies bold format
CTRL + 1Opens the Format Cells dialog box
CTRL + IApplies Italic format
CTRL + Shift + ~Applies general format
CTRL + Shift + $Applies currency format
CTRL + Shift + %Applies percent format
CTRL + Shift + ^Applies scientific format
CTRL + Shift + #Applies date format
CTRL + Shift + @Applies time format
CTRL + Shift + !Applies number format

3. Absolute vs Relative vs Mixed cell referencing

Absolute referenceFixing the value of a particular cell reference. Cell reference are preceded by $.
Relative referenceThe referenced cells are moving down as formula moves down
Mixed cell referenceOnly part of the reference is fixed, either the row or the column, and the other part is relative

4. Cell Modes

ReadyDefault mode , when you are not doing anything
EnterThe moment we begin typing text or value it automatically switches to enter mode
PointWhen begin with = or + or - sign, it switches to enter mode, pressing any of the arrow keys , it switches from enter mode to point mode
EditIf we return to a cell that contains data and press F2 or click in a formula bar, we are placed in edit mode

5. Possible data types

Excel continually analyses what you write and categorises it as one of three potential data types: text, value, or formula.

  1. If Excel recognises an item as a formula, it calculates the formula automatically and shows the result in the worksheet column (you continue to see the formula itself, however, on the Formula bar).

  2. If Excel detects that the item is not a formula, it assesses whether it should be categorised as text or a value.

Excel distinguishes between text and values in order to determine how to align the item in the worksheet. Text entries are aligned with the cell's left edge, whereas values are aligned with the cell's right edge.
