“VLOOKUP finds information from a large table quickly and accurately.”

Syntax of VLOOKUP Function

=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

Explanation of Each Argument

1. Lookup_value

The value you want to search.

It can be a number, text, or cell reference.

Example: Roll Number, Employee ID, Product Code.

2. Table_array

The complete data range where Excel will search.

The first column must contain the lookup value.

3. Col_index_num

The column number from which you want the result.

Counting starts from the first column of the table.

4. Range_lookup

Optional argument.

TRUE (or 1) → Approximate match

FALSE (or 0) → Exact match (most commonly used)

Types of VLOOKUP

1. Exact Match VLOOKUP

Used when the lookup value must match exactly.

=VLOOKUP(A2, A2:D10, 3, FALSE)

2. Approximate Match VLOOKUP

Used when data is sorted and an exact match is not required.

=VLOOKUP(A2, A2:D10, 2, TRUE)

 AUTOFILTER

The AutoFilter is not as well known to most Excel users but is a useful function for quickly viewing your data.

Why use a filter?

Filtering lets you explore data in Excel by allowing you to view the data that meets your chosen criteria. Excel's AutoFilter function makes it easy to hide everything in a database except the records you want to see.

When you choose the AutoFilter command, Excel inserts drop-down list buttons to every cell with a field name in that row. This will allow you to filter all your columns. To add a filter on one particular range of data, first highlight the column of information you wish to filter and then select AutoFilter.

The steps for creating a Filter 

Open the file excel file with proper data

1. All you have to do to filter a database is:

2. Position the cell pointer some place on the worksheet

3. Go to menu DATA-FILTER-AUTOFILTER as shown below

4. Click any columns drop-down list button (top right of each column) to open a list box containing all the entries made in that field and select the one you want to use as a filter. You can note that Excel inserts a drop-down list buttons to every column. This will allow you to do filter one or many columns.

5. Excel then displays only those records that contain the value you selected in that field (all other records are temporarily hidden). The example below shows a multiple filter to view only the cold chain equipment in Makete district that was purchased in 1995.

The Filter criteria's were District (selecting Makete) and Year (selecting 1995). Try this on the Cold Chain worksheet.

6. When you want to display all the records in the database again, choose menu DATAFILTER

→ SHOW ALL.

Alternatively you can also remove a filter from a particular field by selecting its drop-down list button and then selecting the "All" option at the top of the drop-down list.
