Best Free Excel to JSON Converter in 2026 — What Reddit Users Actually Use
Table of Contents
If you search "excel to json converter reddit" you'll find threads spread across r/learnpython, r/excel, r/webdev, and r/dataengineering. The recommendations aren't one-size-fits-all — they depend on what you're doing and how technical you are. This roundup collects the patterns from those threads and gives you a clear answer for each scenario.
For Non-Coders: What Reddit Says to Use
For people who want to convert an Excel file to JSON without writing any code, Reddit's most common advice is: just use an online browser-based converter. The specific tools mentioned most often have changed over the years (several have been paywalled or shut down), but the consistent advice is: find one that processes locally, doesn't upload your file, and outputs clean JSON.
Our free Excel to JSON converter matches exactly what Reddit describes as ideal: no upload to any server, no signup, no limits, and JSON output in under 5 seconds. It handles .xlsx, .xls, .csv, and .ods files, detects types automatically, and lets you pick which sheet to convert.
For Python Developers: The Reddit Consensus
In developer-focused subreddits, pandas is the overwhelming recommendation for programmatic Excel-to-JSON conversion:
import pandas as pd
df = pd.read_excel('file.xlsx')
df.to_json('output.json', orient='records', indent=2)
The main debate in those threads is usually about date handling (pandas outputs datetime objects by default) and how to handle multi-sheet workbooks. For a deep dive on the tradeoffs, see our Python vs browser tool comparison.
A secondary recommendation in r/learnpython is openpyxl for when you need more control over cell-level reading than pandas provides.

A few named tools come up in Reddit threads — BeautifyTools Excel to JSON and Aspose.Cells are the most common. Here's an honest assessment:
BeautifyTools: Gets the job done for simple files. Reddit mentions it frequently because it's been around a long time and ranks high in search. The main complaints are ads and occasional slowness on larger files. It does upload your file to their servers.
Aspose: High quality output, handles complex Excel features well. The online version has file size limits on the free tier and uploads your file to Aspose's servers. Good for edge cases like complex formulas or embedded objects. Overkill for straightforward data tables.
Our tool: No upload, no limits, no ads. Handles the 90% case (flat data tables in .xlsx format) perfectly. Where it doesn't help: if you need the full Excel formula engine, embedded objects, or truly nested JSON output from cross-sheet references.
VS Code and Editor-Based Options
Developer subreddits also recommend VS Code extensions. The "Excel Viewer" extension lets you view .xlsx files inside VS Code, but doesn't directly export to JSON. You'd then need a separate step or a CSV intermediate.
An increasingly popular Reddit suggestion for VS Code users is to install the "Excel to JSON" extension — it adds a right-click context menu option to convert any .xlsx to .json. If you live in VS Code, this is frictionless.
For viewing and converting Excel files without VS Code, the browser tool is faster — no extension installation, works anywhere.
What Reddit Gets Wrong About Excel to JSON
One common piece of bad advice in older threads: "just open Excel, save as CSV, then convert CSV to JSON." This works but it adds a step. Direct Excel-to-JSON conversion preserves type information better — numbers stay numbers, booleans stay booleans. When you go through CSV, everything becomes a string and you lose type fidelity.
Another wrong assumption is that all online converters work the same way. Many upload your file to a server. For financial data, customer lists, or anything sensitive, this matters. The browser tool handles everything locally — functionally equivalent to a desktop app in terms of data privacy.
For CSV to JSON specifically, use our dedicated CSV to JSON converter if your source is already CSV. It's faster than going through Excel first.

Open Free Excel to JSON ConverterFrequently Asked Questions
Is the WildandFree Excel to JSON converter mentioned on Reddit?
The site is newer than many of the older Reddit threads. But it matches the criteria Reddit users consistently describe as ideal: local processing, no upload, free, no ads. You can verify the no-upload claim yourself using browser devtools (Network tab) — no POST requests are made when you convert a file.
What about tools that claim to handle 50,000+ row Excel files?
Large files are more about RAM than tool quality. A browser-based tool and a Python script will both struggle with truly enormous files (500,000+ rows). For those, database-level tools (DuckDB, BigQuery) are more appropriate. For typical business files under 100,000 rows, any of the recommended tools work fine.
Why do some Reddit threads recommend going Excel → CSV → JSON instead of direct conversion?
This was more common when direct Excel-to-JSON tools were rarer or lower quality. Today, direct conversion preserves type information better than the two-step approach. Unless you need CSV for a specific reason, skip the intermediate step.
Can the converter handle Excel files with merged cells or formulas?
Formulas: yes — the tool reads calculated cell values, not the formulas themselves. Merged cells: the top-left cell of a merged range gets the value; other cells in the range appear as null. For clean JSON, unmerge cells before converting.
