Excel or Postman First — What Beginners Should Pick
Quick summary — Excel or Postman first?
Excel and Postman are not competitors — they solve different problems. Excel is for working with data in tables. Postman is for sending, testing, and documenting API requests. The right first pick depends on the role you want, not on which tool is "better".
In this guide you will learn:
- What Excel actually is — and who uses it.
- What Postman actually is — and who uses it.
- Key differences — a side-by-side comparison.
- How they fit into real work — where each one shows up.
- Which to learn first — a practical decision guide.
SECTION 01What Excel is — and who uses it
Excel is Microsoft's spreadsheet tool. You use it to store, clean, calculate, and visualise data in rows and columns. It's the most widely used data tool in the world.
| Question | Answer |
|---|---|
| What it is | A spreadsheet application |
| Runs on | Desktop (Windows/Mac) and the browser (Excel Online) |
| You use it for | Data entry, cleaning, formulas, pivot tables, charts |
| Works with | Cells, rows, columns, formulas, pivot tables |
| Typical users | Analysts, finance teams, operations, HR, students |
=SUMIFS(Sales[Amount], Sales[Region], "North", Sales[Month], "Jan")
=VLOOKUP(A2, Customers!$A$2:$D$100, 3, FALSE)
=IF(B2>=90, "Pass", "Fail")What these do:
- SUMIFS: total sales in the North region for January
- VLOOKUP: pull a customer's city from a lookup table
- IF: return "Pass" or "Fail" based on a score
Simple formulas → charts → pivot tables.
That's the Excel learning curve for beginners.SECTION 02What Postman is — and who uses it
Postman is an API client. You use it to send HTTP requests, inspect responses, organise collections, and automate API testing — without writing a full application first.
| Question | Answer |
|---|---|
| What it is | An API development and testing tool |
| Runs on | Desktop and web |
| You use it for | Sending requests, testing APIs, documenting endpoints |
| Works with | HTTP methods, headers, JSON, collections, environments |
| Typical users | Backend developers, testers, QA engineers, technical writers |
Method: GET
URL: https://api.example.com/users
Headers: Authorization: Bearer <token>
Response (200 OK):
{
"users": [
{ "id": 1, "name": "Asha" },
{ "id": 2, "name": "Rahul" }
]
}What Postman lets you do:
- Try a request without writing code
- Save requests into collections
- Reuse variables across environments
- Add tests as small scripts
- Share the collection with your teamSECTION 03Key differences — side by side
The shortest way to say it: Excel handles data, Postman handles API requests. Here is the full comparison.
| Feature | Excel | Postman |
|---|---|---|
| Type | Spreadsheet application | API client |
| Layer | Data and reporting | API development and testing |
| Runs on | Desktop and browser | Desktop and web |
| Main job | Store and analyse tabular data | Send and test HTTP requests |
| Output | Reports, charts, summaries | API responses, test results, collections |
| Competitors | Google Sheets, LibreOffice | Insomnia, cURL, Bruno |
| Used by | Analysts, finance, operations, HR | Backend devs, testers, QA engineers |
Excel task:
- You have 5,000 order rows
- You need monthly revenue by region
- You build a pivot table
- You add a chart
No code. No API. Just data.Postman task:
- A backend team has exposed /orders
- You need to check the endpoint returns 200
- You send a GET request
- You save the collection for regression tests
No spreadsheet. Just HTTP.SECTION 04How they fit into real work
In most companies, Excel and Postman appear in different roles — and often in the same project, at different stages.
| Role | Uses Excel for… | Uses Postman for… |
|---|---|---|
| Data analyst | Daily work — cleaning, pivots, dashboards | Occasionally, to pull data from an API |
| QA engineer | Test data sheets, result logs | API testing and collections |
| Backend developer | Rarely — usually just exports | Daily — building and testing endpoints |
| Business analyst | Requirements, data review | Rarely — mostly for demos |
| Operations / HR | Daily work — lists, reports | Almost never |
Excel in a typical week:
- Clean and merge exports from three systems
- Build a pivot table for a manager
- Add a chart to a monthly report
- Fix a broken formula someone else left
- Prepare a template for next month
Excel work is steady, daily, and broad.Postman in a typical week:
- Try a new API endpoint
- Debug a 400 error with a teammate
- Add tests to a saved collection
- Re-run the collection before a release
- Update environment variables for staging
Postman work is project-driven and focused.SECTION 05Which should you learn first?
There is no universal answer. Pick based on the role you're aiming for — not on which tool sounds more "technical".
| If you want to… | Start with |
|---|---|
| Work in data analysis, finance, operations, or HR | Excel |
| Move into QA, API testing, or backend development | Postman |
| Become a full-stack developer | Postman first, then Excel as needed |
| Change careers from a non-tech role into IT | Excel first |
| Test APIs at work this quarter | Postman |
Excel starting path:
1. Cells, rows, columns, basic formulas
2. SUM, AVERAGE, COUNTIF, IF
3. VLOOKUP / XLOOKUP
4. Pivot tables
5. Charts and dashboards
Realistic time: 2–3 weeks to be usefulPostman starting path:
1. What HTTP is — methods, status codes
2. Send a GET and a POST request
3. Headers, query params, JSON body
4. Save requests into a collection
5. Environments and variables
Realistic time: 1–2 weeks to be usefulSECTION 06Interview Q&A — Excel vs Postman
Q1Is Postman a replacement for Excel?
No. They solve different problems. Postman sends and tests API requests; Excel stores and analyses data. Neither replaces the other.
Q2Do I need to know Excel before learning Postman?
No. They are independent tools. But if you plan to work with test data or report on API test results, basic Excel skills help.
Q3Which is more useful for a QA role?
Both matter. Excel is used for test data and result tracking; Postman is used for API testing. Many QA roles expect working knowledge of both.
Q4Which is harder for beginners?
Neither is hard to start. Postman requires understanding HTTP basics, which can feel new. Excel feels familiar to most people, so it's often the easier first step.
Q5Can I learn both at the same time?
Yes. They don't conflict. If you're learning QA, it's common to pick up Excel for test data and Postman for API testing in the same month.

SECTION 08Frequently asked questions
What is Postman in simple terms?
Postman is a tool for sending HTTP requests to an API and inspecting the response. It is used for testing and documenting APIs without writing a full application.
Can I use Excel to test APIs?
Not directly. Excel can store and analyse data returned from an API, but it isn't the right tool for sending requests or testing endpoints. Use Postman for that.
Is Excel still worth learning in 2026?
Yes. Despite new tools, Excel remains one of the most widely used data tools in companies. It's a safe, portable skill that applies across nearly every role.
Do I need to know coding to use Postman?
No. Basic Postman use is point-and-click. You can add small JavaScript-based tests later, but that isn't required to start.
Which one should a complete beginner pick?
If you're unsure about your career direction, start with Excel. It's used almost everywhere and is the lower-risk first skill. Pick Postman when you know you want to work with APIs or QA.
