You and your organization are “data-driven,” proper? Certainly, which means utilizing probably the most refined know-how for dealing with knowledge. Having a database in place and querying it with SQL looks as if a minimal requirement in that world.
However what if there are circumstances when a easy spreadsheet beats a rigorously written question by a mile? Listed below are a number of real-life conditions.

1. Your Information Is Small and/or One-Off
Examples of such knowledge embrace:
- A CSV from a vendor
- A monetary mannequin with just a few hundred rows
- A easy finances forecast
- A job tracker

It might be virtually weird to load such knowledge right into a database and run a few queries. It’s overkill. Open it in Excel or Google Sheets, and you may rapidly filter, kind, and carry out calculations and transformations. You’d in all probability nonetheless be organising tables, indexes, and schemas in a database.
2. You Want Pace and Zero Setup
In case you don’t have a relational database in place, setting it up requires:
- A working database, native or cloud
- Outlined tables and datatypes
- Correct permissions
With spreadsheets? None of that. Even when set up is required, it’s a lot faster. However you in all probability don’t want to put in something, as your machine seemingly comes with a pre-installed spreadsheet program, or you may simply use a cloud model.

You merely click on the file and get transferring—particularly when you simply have to see what’s in it or run just a few fast calculations.
3. You Must Collaborate
Databases can deal with collaboration, however they require setting permissions, defining roles, and SQL information.
For instance, collaboration in Google Sheets is way simpler:
- Share a hyperlink together with your collaborators
- Add feedback
- Monitor file adjustments

In case your collaborators are exterior the information staff (e.g., finance, advertising and marketing, operations), chances are high they don’t use SQL — with spreadsheets, that doesn’t matter.
4. You Wish to Visualize and Current Information
SQL is for querying and knowledge evaluation, but it surely’s not nice for presenting your findings. Normally, you’d export the output of your queries elsewhere. Mockingly, it’s usually spreadsheets we have been making an attempt to keep away from.
If visualizing and presenting knowledge is necessary and you may carry out evaluation comparatively simply in a spreadsheet, then select it over SQL. Spreadsheets are each calculation and presentation instruments.

Usually, you’d select spreadsheets over SQL when you want:
- Charts for a presentation
- Pivot tables for executives
- A monetary forecast mannequin
5. Your Work Is Iterative and Messy
Examples of such work are constructing fashions, brainstorming eventualities, and testing assumptions. That is the place I’d use spreadsheets.

You need to use them to:
- Brainstorm monetary eventualities -> copy the sheet, tweak just a few cells, and immediately see the outcomes
- Testing assumptions -> write two formulation, examine them, delete the weaker one; no schema migration wanted
- Fast what-if fashions -> construct a tough model in a spreadsheet earlier than formalizing it in SQL
- Advert-hoc annotations -> color-coding, leaving feedback, highlighting knowledge
- Components iteration -> simply change =SUM(A1:A52) to =AVERAGE(A1:A52); no have to rewrite queries or validate syntax
6. Your Viewers Doesn’t Converse SQL
Firm leaders, undertaking managers, and exterior purchasers are way more more likely to open a spreadsheet than a database.

With spreadsheets, they get one thing they will learn, tweak, and share with out studying a programming language they didn’t intend to be taught.
7. You Contemplate Value and Entry
Sustaining relational databases in manufacturing environments will be pricey; consider cloud storage, compute assets, and admin time.

Spreadsheets are free or virtually free. In case your dataset and evaluation are one thing a spreadsheet can deal with comparatively simply, then selecting it over SQL avoids overhead.
8. You Want Fast Information Entry
Databases aren’t designed for simple handbook row-by-row enter. You’d both have to put in writing a question or import knowledge from, guess what, a spreadsheet.

Typing knowledge straight right into a spreadsheet is less complicated if you would like, for instance, to:
- Document assembly notes
- Acquire a number of gross sales leads
- Monitor to-dos or deadlines
Conclusion
One of the best ways is, after all, to mix each spreadsheets and SQL. The latter is for heavy knowledge processing, transformation, and evaluation, particularly if it entails repetitive duties; then it pays off to ascertain a logical question and easily re-run it when required. In case you’re simply beginning out or want a refresher, this SQL cheat sheet is a good useful resource for core ideas you’ll truly use.
Spreadsheets are higher while you’re on the lookout for agility, fast understanding of knowledge, lighter analyses, fast knowledge visualizations, and sharing.
