About the 2022 Microsoft Excel Builders Challenge

If you remember Tiller’s previous Builders Challenges, this one is a bit different. Rather than accepting entries and reviewing them at the end of a submission period, we will now award prizes within 5 business days of builder submissions.

Prize level will be determined based on the quality, ambition, and value of your solution.

Simplified Schedule Kicks off Today

The Excel Builders Challenge kicks off today, and we are now accepting submissions. Submissions are open until June 6, 2022.

The sooner you share your Tiller-powered Excel creation, the sooner you can claim your prize. We can’t wait to see what you build! Prize levels, awarded at Tiller’s discretion, include:

  • Tiller t-shirt
  • $25 gift card
  • 1-year Tiller subscription extension
  • $100 gift card
  • $500 cash
  • $1,000 cash

Judging Criteria

Prizes will be awarded by Tiller’s judging panel based on:

  • Value of concept to the personal-finance community
  • Value & quality of Tiller integration
  • Uniqueness of concept vision
  • User experience & usability

Hey @randy , will data modelling in Power Query count as scripting? It’s built-in to Excel 2016+, and available as an add-on apparently for 2010 Professional Plus (my stomach churned at the old “Pro”, “Pro Plus”, “Home”, … MS Product Naming schemes, :clap: MS improving that, “Windows 10” and “Windows 10 Pro” is perfect :+1:).

I made a proof-of-concept PowerBI Connector for Moodle, to analyze my son’s Grade’s in near real-time, with far more info available than the school login website shows. Really wrapped my head around Power Query.

This morning, after starting a competition entry, in hopes of winning or impressing the Tiller Team, (yes, all ~16 of you, according to LinkedIn), I stumbled on a familiar looking Power Query editor window in Excel by accident. I believe I was messing with Named Ranges. Anyways, BLEW MY MIND :exploding_head:

I am working on a Data Importer, and future Exporter (pre-defined CSV formats, Quicken QIF, Quickbooks QFX/OFX, Moneydance, Moneyspire, ledger-cli (:crown: of data sovereignty in my mind), etc…).

Biggest thing, that actually finally led me to Tiller, is that DOES NOT OFFER AN OFX DOWNLOAD, or a standard CSV. Their date format is ‘02 FEB 22’ or something like that. Quicken won’t import, Quickbooks won’t, Moneydance, Moneyspire, but I think PocketSmith might have (my pick after Tiller at the moment).

Anywho, ummm, man. I have been at this all day, plus finished wall trim in my garage :slight_smile: :sleeping:

Right… so that led me to reconstructing the Tiller Transactions Worksheet into a a Power Query Table, along with an ImportSource sheet/table, and a column mapping sheet/table/query that I am still working out issues with, but still a week to go.

You can see my entries #WIP repo at


There is some sensitive account info in there that I will scrub, but it’s a semi-dummy account so no biggie.

Anyways, my mind was blown again when I realized there was no need for an IMPORT button, since the mappings were all being done on the fly in Excel Power Query transformations, merges, Table.GroupBy (to de-dupe entries), etc…

Am I onto something here?

Before this challenge, I found Tiller, in my ~3 weeks of using it now, limiting compared to the several other options I have reviewed, some listed in my previous sentences, is ANALYTICS and a MOBILE APP.

I was going to use Microsoft Power BI to create some beautiful, mobile friendly (portrait and landscape custom), themeable, Power BI Dashboards that could be live refreshed thanks to Microsoft 365 and OneDrive.

Wow, okay, anyway…


Can Excel’s Power Query be used as part of this challenge? Is it considered scripting? Is it good? Can I haz job yet?
