Understanding Data Entry and Formatting in Excel

Intro

This guide focuses on practical steps for mastering data entry and formatting in Excel to ensure accuracy and consistency in any project.

Step-by-Step Instructions

1. Data Entry

• Open Excel: Launch the Excel application.
• New Workbook: Click 'File' > 'New' > 'Blank Workbook'.
• Entering Text:
  • Click on a cell (e.g., A1).
  • Type the desired text (e.g., "Name") and press Enter.
• Entering Numbers:
  • Click on the next cell (e.g., A2).
  • Type the number (e.g., "100") and press Enter.

2. Formatting Cells

• Text Formatting:
  • Select the cell(s) containing text.
  • Use the toolbar to set font type, size, bold, italics, underline.
• Number Formatting:
  • Select the cell(s) containing numbers.
  • Right-click and select 'Format Cells'.
  • Choose the 'Number' tab and select the appropriate category (e.g., Number, Currency, Date).

3. Formatting Columns and Rows

• Adjusting Column Width:
  • Click on the letter header of the column (e.g., A).
  • Place the cursor at the edge until it becomes a double-sided arrow.
  • Click and drag to adjust the width.
• Adjusting Row Height:
  • Click on the number header of the row (e.g., 1).
  • Place the cursor at the edge until it becomes a double-sided arrow.
  • Click and drag to adjust the height.

4. Using Fill Handle

• Fill Handle for Series:
  • Enter a starting value in a cell (e.g., A1: 1).
  • Select the cell, then drag the fill handle (small square at the bottom-right corner) down or across to fill the series.

5. Quick Formatting Techniques

• Quick Format Cells to Currency:
  • Select the target cells.
  • Use the shortcut Ctrl + Shift + $.
• Quick Format Cells to Percentage:
  • Select the target cells.
  • Use the shortcut Ctrl + Shift + %.

6. Basic Formula Usage

• Sum:
  • Click on a cell where you want the sum.
  • Type =SUM(A1:A10) assuming you want to sum values from A1 to A10.
  • Press Enter.
• Average:
  • Click on a cell where you want the average.
  • Type =AVERAGE(A1:A10).
  • Press Enter.

7. Conditional Formatting

• Apply Conditional Formatting:
  • Select the cells to format.
  • Click on 'Home' > 'Conditional Formatting'.
  • Choose a rule (e.g., Highlight Cells Rules > Greater Than).
  • Enter the criteria and select the format.
  • Click 'OK'.

Practice Exercises

• Exercise 1:

  • Create a new workbook.
  • Enter a list of 10 items in column A.
  • Format the text to be bold and size 12.
  • In column B, enter corresponding prices and format as currency.
  • Sum the prices in cell B12.

• Exercise 2:

  • Create a date range from January 1 to January 10 in column A using fill handle.
  • Format the dates to 'dd-mmm-yy'.
  • Average the values in column B and display the result in cell B12.

This concludes Part #1 of the project. Continue practicing to solidify your understanding of data entry and formatting in Excel.

Using Basic Formulas for Data Calculations in Excel

Sum Function

Calculates the total sum of a range of cells.

=SUM(A1:A10)

Average Function

Finds the average (mean) of a range of cells.

=AVERAGE(B1:B10)

Count Function

Counts the number of cells in a range that contain numbers.

=COUNT(C1:C10)

Max Function

Finds the maximum value in a range of cells.

=MAX(D1:D10)

Min Function

Finds the minimum value in a range of cells.

=MIN(E1:E10)

IF Function

Checks whether a condition is true, and returns one value if true and another if false.

=IF(F1>10, "Greater than 10", "10 or less")

VLOOKUP Function

Looks up a value in the first column of a range, and returns a value in the same row from a specified column.

=VLOOKUP(G1, A1:D10, 3, FALSE)

HLOOKUP Function

Looks up a value in the top row of a range, and returns a value in the same column from a specified row.

=HLOOKUP(H1, A1:D10, 3, FALSE)

CONCATENATE Function

Joins several text strings into one text string.

=CONCATENATE(I1, " ", J1)

LEFT Function

Returns the first character(s) from the left side of a text string.

=LEFT(K1, 3)

RIGHT Function

Returns the last character(s) from the right side of a text string.

=RIGHT(L1, 2)

MID Function

Returns a specific number of characters from a text string, starting at the specified position.

=MID(M1, 2, 4)

TODAY Function

Returns the current date.

=TODAY()

NOW Function

Returns the current date and time.

=NOW()

LEN Function

Returns the number of characters in a text string.

=LEN(N1)

TRIM Function

Removes extra spaces from a text string, leaving only single spaces between words.

=TRIM(O1)

These formulas are foundational tools for data calculations and analysis in Excel. Use them directly within your spreadsheet to perform calculations effectively.

Advanced Formulas for Enhanced Data Manipulation in Excel

1. Nested IF Statements

Perform multiple conditions checks.

=IF(A1 > 90, "A", IF(A1 > 80, "B", IF(A1 > 70, "C", "D")))

2. VLOOKUP for Data Fetching

Retrieve related data from different tables.

=VLOOKUP(B2, Table1!A:B, 2, FALSE)

3. INDEX-MATCH Combination

A more flexible lookup than VLOOKUP.

=INDEX(A:A, MATCH("LookupValue", B:B, 0))

4. CONCATENATE Text Strings

Merge data from separate cells.

=CONCATENATE(A2, " ", B2, " ", "Example")

5. SUMIF/SUMIFS for Conditional Summation

Sum numbers based on criteria.

=SUMIF(A:A, ">100", B:B)

=SUMIFS(C:C, A:A, ">100", B:B, "<200")

6. COUNTIF/COUNTIFS for Conditional Counting

Count cells based on criteria.

=COUNTIF(A:A, ">=50")

=COUNTIFS(A:A, ">=50", B:B, "<=100")

7. TEXT Function

Format numbers as text.

=TEXT(A2, "0.00")

8. Array Formulas for Advanced Calculations

Perform batch operations on multiple cells.

=SUM(A2:A10 * B2:B10) // Press Ctrl+Shift+Enter

9. LEFT, MID, RIGHT for Substring Extraction

Extract parts of text strings.

=LEFT(A2, 3)

=MID(A2, 2, 5)

=RIGHT(A2, 4)

10. IFERROR for Error Handling

Catch and handle errors in formulas.

=IFERROR(VLOOKUP("Value", A:B, 2, FALSE), "Not Found")

11. Dynamic Named Ranges with OFFSET

Create ranges that expand automatically as data grows.

OFFSET(Sheet1!$A$1, 0, 0, COUNTA(Sheet1!$A:$A), 1)

12. Use of AND/OR in Conditional Statements

Combine multiple conditions.

=IF(AND(A2 > 50, B2 < 100), "Pass", "Fail")

=IF(OR(A2 > 50, B2 < 100), "Pass", "Fail")

These advanced formulas enhance your ability to manipulate and analyze data effectively in Excel.
