Timesheets are like TPS reports* of any project. Team members think of them as an annoying activity. For managers, timesheets are a vital component to understand how team is working and where the effort is going. I will not get in to the merits and pitfalls of timesheets. However, I feel that by using Microsoft Excel capabilities you can create a truly remarkable timesheet tracking tool and still leave your team members un-annoyed.
In this tutorial we will learn 3 things about timesheets and resource management using Excel
- How to setup a simple timesheet template in excel?
- How to make a more robust timesheet tracker tool in Excel?
- How to use the timesheet data to make a resource loading chart?
1. Make a Simple Excel Timesheet Template
According to Wikipedia, timesheets are used for
Timesheets may record the start and end time of tasks, or just the duration. It may contain a detailed breakdown of tasks accomplished throughout the project or program. This information may be used for payroll, client billing, and increasingly for project costing, estimation, tracking and management.
By defining a simple and straight forward template in Excel and using it to track time (or efforts) in your projects, you can easily consolidate the data, compare efforts and make any necessary analysis.
At its simplest form, the timesheet is nothing but list of team members and list of activities in a matrix. Look at the below example:
You can easily create such template in excel.
2. A More Robust Excel Timesheet Tracker
While the time sheet format shown in the above section is good, it is a wrong format if you need to analyze the timesheet entries of a 100 member project. Also in large projects usually members do few activities at a time. That means the above format (in section 1) will result in a sparse matrix.
Using a tracker log format is much more convenient to both record and analyze timesheet entries. Look at the example below:
We can use excel features like data validation drop downs, shared workbooks to make the timesheet entry and management a breeze.
3. Create a Resource Loading Chart – Project Management
Resource loading charts are a good way to show how busy the team members are in a project. At the outset the resource loading chart is nothing but a heatmap.
Look at an example resource loading chart below:
You can make a resource loading chart in MS Excel by following the below steps:
- The pre-condition for the resource loading chart is that we have clear data available to make one. This is where the robust timesheet tracker shown in section 2 of this post comes handy.
- First create a blank table in excel with team member names in first column and week numbers in first row. (Please note, you can make other types of resource loading charts by changing the Row and Column headers. For eg. You can show resource loading by Project and Team member)
- Assuming we have the time sheet data in the format shown in Section 2,
- Assuming “log_member_names” refers to the member name column and log_weeknum refers to the last column in the timesheet, we can write a simple COUNTIFS formula like this =COUNTIFS(log_member_names, “John Galt”, log_weeknums, 3)
- Once we calculate values for all team members using the above formula, we can apply conditional formatting to make the heat map. In Excel 2016 / 365, this is one step.
- That is all.

What Next?
Timesheets are a great way to understand how the effort is spent. Even though project estimation models have become more and more effective, still lots of projects are overshooting budgets and timelines. And this is where timesheets can help you as a manager. While estimation looks in to future, timesheets look at past. Timesheets give feedback to your estimation models. This can help you in making better estimates in future.
In the next installment of this series, learn about tracking issues and risks using excel spreadsheets.

Your thoughts and suggestions?
What are your ideas about timesheets using excel? Does your organization use excel as a way to manage timesheets or do you use some time tracking software? What is the granularity of detail captured in timesheets? As a project manager, what use do you find in time sheet data?

Some great contributions here.
Gotta love the Friday 13th formula 😀
Great tips from you all! Thanks a lot for sharing! bsamson, particularly you helped me on a terribly annoying task. 🙂
(BTW, Chandoo, it's not exactly "Find if a range is normally distributed" what my suggestion does. It checks if two proportions are statistically different. I probably gave you a bad explanation on twitter, but it'd be probably better if you fix it here... 🙂 )
Great compilation Chandoo
For the "Clean your text before you lookup"
=VLOOKUP(CLEAN(TRIM(E20)),F5:G18,2,0)
I would like to share a method to convert a number-stored-as-text before you lookup:
=VLOOKUP(E20+0,F5:G18,2,0)
@Peder, yeah, I loved that formula
@Aires: Sorry, I misunderstood your formula. Corrected the heading now.
@John.. that is a cool tip.
Hey Chandoo,
That p-value formula is really great for a statistics person like me.
What a p-value essentially is, is the probability that the results obtained from a statistical test aren't valid. So for example, if my p value is .05, there's a 5% probability that my results are wrong.
You can play with this if you install the Data Analysis Toolpak (which will perform some statistical tests for you AND provide the P Value.)
Let's say for example I've got two weeks of data (separated into columns) with the number of hours worked per day. I want to find out if the total number of hours I worked in week two were really all the different than week one.
Week1 Week2
10 11
12 9
9 10
7 8
5 8
Go to Data > Data Analysis > T-Test Assuming Unequal Variances > OK
In the Variable 1 Box, select the range of data for week 1.
In the Variable 2 Box, select the range of data for week 2.
Check "Labels"
In the Alpha box, select a value (in percentage terms) for how tolerant you are of error.
.05 is the general standard; that is to say I am willing to accept a 95% level of confidence that my result is accuarate.
Select a range output.
Excel calculates a number of results: Average (mean) for each week's data, etc.
You'll notice however that there are two P Values; one-tail and two-tail. (one tail tests are for > or .05), the number of hours I worked in week two is statistically equivalent to the number of hours I worked in week one.
So here’s a way you might want to use this. You put up a new entry on your blog. You think it’s the best entry ever! So you pull your webstats for this week and compare it to last week. You gather data for each week on the length of time a visitor spends on your website. The question you’re trying to prove statistically is whether there’s an average increase in the amount of time spent on your website this week as compared to last week (as a result of your fancy new blog post). You can run the same statistical test I illustrated above to find out. Incidentally, it matters very little to the stat test whether the quantity of visitors differs or not.
Anyhow, the Data Analysis toolpack doesn't perform a lot of stat tests that folks like me would like to have access to. In those cases I have to either use different software, or write some very complicated mathematical formulas. Having this p-value formula makes my life a LOT easier!
Thanks!
Eric~
Fantastic stuf..One line explanation is cool.
Thanks to all the contributors
OS
Take FirstName, MI, LastName in access (you can fix it to work in excel) capitalize first letter of each and lowercase the rest and add ". " if MI exists then same for last name:
Full Name: Format(Left([FirstName],1),">") & Format(Right([FirstName]),Len([FirstName])-1),"") & ". ","") & Format(Left([LastName],1),">") & Format(Right([LastName],Len([LastName])-1),"<")
I teach excel, access, etc etc for a living and i have my access students build this formula one step at a time from the inside out to show how formulas can be made even if it looks complicated. Yes I know I could just do IsNull([MI]) and reverse the order in the Iif() function but the point here is to nest as many functions as possible one by one (also I illustrate how it will fail without the Not() as it is)
Extract the month from a date
The easiest formula for this is =MONTH(a1)
It will return a 1 for January, 2 for February etc.
if in a column we write the value of total person for eg. 10 if we spent 1.33 paise each person then how we get total amount in next column and the result will in round form plzzzzz solve my problem sir................... thank u
@Anjali
If the value 10 is in B2 and 1.33 paise is in C2 the formula in D2 could be =B2*C2
If the values are a column of values you can copy the formula down by copy/paste or drag the small black handle at the bottom right corner of cell D2
kindly share with me new forumulas.
