Export Postman API Response to Excel — Paste JSON, Get .xlsx

You are testing an API in Postman and need the response data in a spreadsheet — for QA review, sharing with a product manager, or building a dataset for analysis. The quickest path is copying the response body from Postman and pasting it into a free browser converter. No Postman script, no Newman, no code. Here is exactly how.

Step 1: Copy the JSON Response Body in Postman

In Postman, after sending a request:

1. Click on the Body tab in the response panel (at the bottom).
2. Set the view to Raw or Pretty — either works. Raw is faster to copy.
3. Click anywhere in the response body, then press Ctrl+A (Windows) or Cmd+A (Mac) to select all.
4. Copy with Ctrl+C / Cmd+C.

Alternatively, there is a small copy icon in the upper right of the response panel — click it to copy the entire response body to your clipboard.

If your response is wrapped (like {"data": [...], "meta": {...}}), you need to copy just the array portion. Switch to the Raw view, find the opening bracket of the array, select from there to the closing bracket, and copy that selection.

Step 2: Paste into the JSON to Excel Converter

Open wildandfreetools.com/spreadsheet-tools/json-to-excel/ in another tab. Paste the JSON into the text area. Click Convert. Download the .xlsx file.

The converter maps each key in the response objects to a column header. A response with 100 records and 8 fields becomes a spreadsheet with 100 rows and 8 columns.

The process takes under 10 seconds for typical API responses (hundreds to a few thousand records). For paginated APIs where you need all pages combined, see the section below on combining paginated responses.

Using a Postman Test Script to Extract Array Responses

If your API returns a wrapper object rather than a plain array, you can use a Postman test script to log just the array:

// Add this to the "Tests" tab in Postman
var responseData = pm.response.json();

// If data is wrapped, extract the array
var records = responseData.data || responseData.results || responseData.items || responseData;

// Log the clean array to console (visible in Postman console)
console.log(JSON.stringify(records));

Open Postman's Console (View > Show Postman Console or Ctrl+Alt+C), run the request, find your logged JSON in the console, copy it from there, and paste into the converter.

This is useful for APIs with consistent wrapper patterns where you always need to extract a specific key.

Why Developers Convert Postman Responses to Excel

The most common use cases:

• QA and testing: Comparing expected vs actual API responses across a set of test cases. An Excel spreadsheet is easier for non-developers to review than raw JSON.
• Data sampling: Quickly reviewing a sample of production data to understand data quality, null rates, and value distributions without writing analysis code.
• Stakeholder reporting: A product manager or client wants to see the data in a readable format. Converting 200 records from an API into a formatted spreadsheet takes 2 minutes.
• Documentation: Capturing an example API response as a formatted table for a technical specification or API documentation.
• Debugging: Comparing the before/after state of data records to verify that an API change had the expected effect.

For all of these use cases, the manual copy-paste approach is fast enough and does not require any Postman collections, Newman setup, or code.

Frequently Asked Questions

My API response has pagination — can I combine all pages into one Excel file?

Not automatically with the browser tool — it processes one JSON array at a time. The workaround is to combine the arrays manually: copy each page response into a text editor, remove the wrapping objects, combine the arrays into one (remove closing ] from page 1 and opening [ from page 2, add a comma between them), and paste the combined array into the converter.

Can I use the Postman Visualizer to create an Excel-like table instead?

Postman has a Visualizer feature that can display response data as an HTML table. This is useful for viewing data within Postman, but you cannot directly download it as .xlsx. The paste-and-convert approach is still faster if you need an actual Excel file.

What about Postman's collection runner — can it export data to Excel?

Postman's collection runner exports test results in JSON or CSV format, not .xlsx. If you run tests with collection data variables, you can export the CSV result and use our CSV-to-Excel converter instead — which may be cleaner for structured test data.
