Once you start using Excel to develop systems, budget, forecast and large tables of data you may come across the dilemma of “How do I know this is right” or “How do I truth check this”.

This post, Huis second, will add a tool to your arsenal to help you out.

The technique below allows for the rapid visual evaluation of 12 or more days/months/years of data via a chart of 2 variables and the ratio between them, utilising 2 sliders to rapidly change input variables.

DATA

Typically all businesses deal in 3 types of numbers, ie: Dates or Times, Physicals and Dollars.

Dates may include Times, Days, Weeks, Months, Years or any periods in between

Physicals directly relate to the business you are in but may include inputs and or outputs: eg: metal, tyres and cars, sugar, flour and cakes or whatever your business makes, strangely Physicals may also include Dollars, if you’re in the financial services sector. People are a Physical.

And Dollars which could be revenue, costs, cashflows or profit types of numbers.

I have found one of the best methods of looking at large tables of data is to look at a key input or output physical and then interactively scroll through the cost or income and calculate a ratio between the two.

I am going to use as an example a budget which has 40 rows of data including Physicals and Costs. But you will see that the techniques here can easily be extended to hundreds of rows. You can download this file here: Bobs Homes

The technique below allows rapid visual evaluation of 12 or more months data a chart of 2 variables and the ratio between them.

Using 2 sliders the user can rapidly move between variables and evaluate the variance over a given time frame against another variable.

The technique involves the charting of 3 ranges which in turn will be controlled by 2 sliders.

The first Range and slider will allow the selection of a Physical.

The second Range and slider will allow the selection of the Cost/Income component.

The third range will be the ratio of these, but specifically cost or income per physical.

I have attached a workbook, Bobs Homes, which contains 2 models, an example model for you to practice the following techniques on and a completed model which you can examine and pull apart to see how it works.

Bobs Homes

Load the model and scroll around and see what data is available. You will notice a time scale across the top with Physicals and Dollars down the left side. The Physicals and Dollars are grouped into common areas like inputs, outputs and costs, income and profit.

You will also note that there are 10 blank rows at the top of the worksheet. I do this so that I can perform simple calculations, charts or other workings without upsetting the data and other calculations below and for macro’s which automatically find the bottom of the data I know there is nothing below my data to upset the calculations.

Let’s jump in

SETUP

We’re going to add the following components

Headings

A2: Physical

A3: Cost/Revenue

A4: Ratio

E1: =E12

and copy across to Q1

Data

C2: 1

C3: 1

D2: =CONCATENATE(OFFSET(B$13,$C$2,0),OFFSET(C$13,$C$2,0))

D3: =CONCATENATE(OFFSET(B$22,$C$3,0),OFFSET(C$22,$C$3,0))

D4: =CONCATENATE(D3,”/”,D2)

E2: =OFFSET(E$13,$C$2,0)

E3: =OFFSET(E$22,$C$3,0)/1000

Copy E2:E4 across to Q2:Q4

Chart

Select Area D1:Q4

Insert Chart, Line Chart with or without markers to your liking

Suggestion – Place the Chart between the Data and the new Headings and formulas you have just added

Adjust the Legend to be at the Bottom of the chart

Sliders

Insert 2 Sliders

Developer Tab, Insert Scroll Bar (Form Control)

If you don’t have the Developer Tab, Have a read of: http://chandoo.org/wp/2009/05/26/excel-2007-productivity-tips/

Position the scroll bars so they are vertically next to the Chart, Use Alt whilst dragging to snap to Cell corners or edges

Link the sliders to the lookup cells

Slider 1
Current value: 1
Minimum: 1
Maximum: 7 (This is the number of Rows of Physicals data)
Incremental Change: 1
Page Change: 0
Cell Link: $C$2

Slider 2
Current value: 1
Minimum: 1
Maximum: 19  (This is the number of Rows of Cost/Revenue data)
Incremental Change: 1
Page Change: 0 (set this to maybe 10 if you have more than 30/40 rows)
Cell Link: $C$3

FINAL MODEL

You can now select a Physical by dragging the Left Scroll bar

You can now select a Revenue/Cost by dragging the Right Scroll bar

The Ratio of Cost/Revenue to the Physical is calculated and the 3 are all charted

Examine the model and see what variances in inputs/outputs can be seen.

HOW DOES THIS WORK?

The Formula in E2:Q3, are extracting the physicals and Cost/revenue data from the main body of the report by simply using an Offset function from the top of the Physicals and Cost/Revenue area.

The Distance they offset is retrieved from the control Cells C2:C3

The labels for the Physicals and Costs/Revenues are also retrieved using 2 Offsets inside a Concatenate. This is done to allow Heading Rows and Sub Headings to be displayed and joined if available from 2 separate columns.

The Chart is a simple Line Chart which is charting the 3 Data Rows (E2:Q4) against the Time Period (E1:Q1) at the top of the work area.

You can customise the chart to your content.

The 2 sliders control the control Cells C2:C3, and allow for interactive selection of Physicals and costs.

In use often you will find that one of the Physicals, Costs/Revenue or Ratio is generally much smaller in scale than the other 2 measures. Generally it is a good idea to plot the odd scale against a secondary Y axis.

Select the series line, Right Click and select Format Data Series

    I use this method very often.
    I always use =SUBSTITUTE (ColumnWithText,"'","''")
    to be sure that potential apostrophe in text columns are doubled as required in SQL.

  2. Chandoo says:

    @Leonid.. that is a good technique to use substitute to clean up text apostrophes. thanks

    Goal:
    Generate update statement in excel where the columns that can be updated are dynamic
    You want the columns which are not updated to keep the same value
    (or not be overwritten with NULL values with the new generated statement)
    the statement can be applied to multiple rows in excel for the same column headers
    (This is why the '$' exist for the column headers that are being set)

    A1 = First_Name
    B1 = Last_Name
    C1 = Middle_Name

    ="
    UPDATE PERSONS "&CHAR(10)&
    " SET 1 = 1 "&CHAR(10)&
    IF(LEN(TRIM($A2))=0,"",", "&$A$1&" = '"&$A2&"'"&CHAR(10))&
    IF(LEN(TRIM($B2))=0,"",", "&$B$1&" = '"&$B2&"'"&CHAR(10))&
    IF(LEN(TRIM($C2))=0,"",", "&$C$1&" = '"&$C2&"'"&CHAR(10))&
    " WHERE name = 'staticordynamicvalue' AND gender = 'staticordynamicvalue'
    "
    Output (if all columns are set):
    UPDATE PERSONS SET 1 = 1,
    First_Name = 'Joe',
    Last_Name = 'ORien',
    Middle_Name = 'Richard'
    WHERE age = 28 AND gender = 'm'

    Output (if only First _Name (A1) is set):
    UPDATE PERSONS SET 1 = 1,
    First_Name = 'Joe'
    WHERE age = 28 AND gender = 'm'

  4. Paul G. says:

    Possibly my post above is confusing without the actual table to look at. I will do the same example with the table used here. Instead of an insert statement I will generate an update statement for the columns, Cust_Name, Phone & E-mail
    where we can generate an update statement for any column individually or together. 🙂 I hope this can help.
    =”
    UPDATE table “&CHAR(10)&
    ” SET 1 = 1 “&CHAR(10)&
    IF(LEN(TRIM($A2))=0,”",”,Cust_Name = ‘”&$B3&”‘”&CHAR(10))&
    IF(LEN(TRIM($B2))=0,”",”, Phone = ‘”&$C3&”‘”&CHAR(10))&
    IF(LEN(TRIM($C2))=0,”",”, E-mail = ‘”&$D3&”‘”&CHAR(10))&
    ” WHERE Cust_Name = ’Bill Gates'

    Thanks, it has been very useful !
    It saved me at least 30 minutes, and time is the most expensive thing in our world...

  6. Kad says:

    Hey Paul,
    What if any of A2, B2, or C2 is a date field?
    The formula above is taking date as string. Any solution?

    • Smitha says:

      Even I faced the same problem. If any of the above columns are date, it is taken  as string. Any work around for this?

  7. Sam Howley says:

    I've found the string concatenation method works well.

    At the risk of sounding spammy I would mention that
    if it's something your are doing regularly it might be worth investigating a tools
    that make it easier, such as QueryCell, an excel add-in I've developed.

    It gives you a right click menu option that will produce and then customize insert statements for the selected region of Excel data.

    Cheers
    Sam

    • Pravin says:

      Hi,
      For inserting the excel data to your SQL table, you can create insert statements in excel file according to your columns.
      then just execute the statements all at once, it will insert the required data to sql server table.
      thanks,

  8. Chetan Patil says:

    I tried to generate t-sql insert queries from the above example
    ="insert into values('" &A2 &"','" & B2& "');"
    but it generates on one record instead of all records from excel sheet.
    I'm using Excel 2003 and the excel sheet contains 922 records.

  9. Mike says:

    Most data bases can generate DDL for any object but not a lot of them allow generation of INSERT statements for the table data.
    The workaround is to make use of ETL Tools for transferring data across servers. However, there exists a need to generate INSERT statements from the tables for porting data.
    Simplest example is when small or large amount of data needs to be taken out on a removable storage media and copied to a remote location, INSERT..VALUES statements come handy.

    There is a number of scripts available to perform this data transformation task. The problem with those scripts that all of them database specific and they do not work with textiles

    Advanced ETL processor can generate Insert scripts from any data source including text files

    If any one can help me out with following.
    I want to know a SQL query of below excel formula:

    names5 63

    if there is a number (29756789) then it should search in sql by taking the prefix of number (297) from (29756789) and return the name field (name4).
    Codes can be of two digit or three.

    Hi I have a question maybe you guys have an answer for me

    ="insert into customers values('" &B3 &"','" & C3 & "','"&D3&"');" where B3, C3, D3 refer to above table data.

    the above technique works but is there a way to write it so it takes a range instead of individual columns. because I have an extremely wide table

    ="insert into customers values(B3:D3);" where B3, C3, D3 refer to above table data.
