You and your organization are “data-driven,” proper? Certainly, meaning utilizing probably the most subtle expertise for dealing with information. 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 here are a number of real-life conditions.

1. Your Information Is Small and/or One-Off
Examples of such information embrace:
- A CSV from a vendor
- A monetary mannequin with a couple of hundred rows
- A easy funds forecast
- A job tracker
Picture by Writer
It might be nearly weird to load such information right into a database and run a few queries. It’s overkill. Open it in Excel or Google Sheets, and you may shortly filter, type, and carry out calculations and transformations. You’d most likely nonetheless be organising tables, indexes, and schemas in a database.
2. You Want Velocity and Zero Setup
If you happen to don’t have a relational database in place, setting it up requires:
- A operating 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 most likely don’t want to put in something, as your machine doubtless comes with a pre-installed spreadsheet program, or you possibly can simply use a cloud model.

You merely click on the file and get shifting—particularly for those who simply have to see what’s in it or run a couple of fast calculations.
3. You Have to Collaborate
Databases can deal with collaboration, however they require setting permissions, defining roles, and SQL data.
For instance, collaboration in Google Sheets is far simpler:
- Share a hyperlink together with your collaborators
- Add feedback
- Monitor file modifications

In case your collaborators are outdoors the info workforce (e.g., finance, advertising, operations), chances are high they don’t use SQL — with spreadsheets, that doesn’t matter.
4. You Need to Visualize and Current Information
SQL is for querying and information evaluation, but it surely’s not nice for presenting your findings. Often, you’d export the output of your queries elsewhere. Paradoxically, it’s typically spreadsheets we have been attempting to keep away from.
If visualizing and presenting information is essential 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 for those who 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 should use them to:
- Brainstorm monetary eventualities -> copy the sheet, tweak a couple of 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 information
- Formulation iteration -> simply change =SUM(A1:A52) to =AVERAGE(A1:A52); no have to rewrite queries or validate syntax
6. Your Viewers Doesn’t Communicate SQL
Firm leaders, venture managers, and exterior purchasers are way more more likely to open a spreadsheet than a database.

With spreadsheets, they get one thing they’ll 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 sources, and admin time.
Picture by Writer
Spreadsheets are free or nearly 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 guide row-by-row enter. You’d both have to write down a question or import information from, guess what, a spreadsheet.
Picture by Writer
Typing information straight right into a spreadsheet is less complicated if you’d 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 information processing, transformation, and evaluation, particularly if it includes repetitive duties; then it pays off to ascertain a logical question and easily re-run it when required. If you happen to’re simply beginning out or want a refresher, this SQL cheat sheet is a superb useful resource for core ideas you’ll truly use.
Spreadsheets are higher whenever you’re on the lookout for agility, fast understanding of knowledge, lighter analyses, fast information visualizations, and sharing.
