About jsonviewer.in - The Ultimate JSON Productivity Suite

Welcome to jsonviewer.in, a robust, client-side web application engineered specifically for developers, data analysts, and automation experts. Our platform solves the common headaches associated with handling raw, minified, or broken JSON payloads from webhooks and APIs.

Intelligent Auto-Fix & Formatting

Dealing with invalid JSON formats can be frustrating. Common issues like missing quotes, trailing commas, or single quotes often break standard parsers. Our advanced editor utilizes the native JSON5 parsing engine to automatically detect and repair structural syntax errors in real-time, transforming messy data into beautifully formatted, readable code without requiring manual debugging.

Advanced JSON to Excel Converter

Migrating complex, deeply nested JSON arrays into structured Excel (XLSX) or CSV files has never been easier. Unlike basic online converters that fail on multi-level objects, our Pro Engine recursively flattens deep nested objects and normalizes inconsistent arrays. This allows you to seamlessly map datasets into clean, visual columns and rows. It is the perfect companion tool for preparing dynamic marketing datasets, e-commerce order logs, or building custom CRM imports. Open the JSON to Excel converter.

100% Secure & Privacy Focused

We understand the importance of data privacy. That is why jsonviewer.in operates entirely within your browser (client-side). Your sensitive API payloads, tokens, and database exports are processed locally on your machine and are never transmitted to or stored on our servers.

Free Online JSON to Excel Converter

Convert JSON to Excel (XLSX) or CSV in seconds, right in your browser. Paste your JSON, upload a .json file, or fetch it straight from an API URL, then download a clean spreadsheet ready for Excel, Google Sheets, or any CRM import.

How to convert JSON to Excel

Paste or drop your JSON into the Data Input panel and click Convert Data. Check the preview, use the Mapper to choose which columns to keep, give your file a name, and click .XLSX or .CSV to download it.

Handles nested and messy JSON

Real API responses are rarely flat. The converter flattens deeply nested objects into readable column names, normalizes arrays whose items have different fields, and lets you switch between multiple tables when your JSON contains more than one dataset. Broken JSON with trailing commas or missing quotes is repaired automatically before conversion.

Private by design

The conversion runs entirely in your browser. Your data is never uploaded to our servers, so it is safe to use with API payloads, order exports, and customer records.

Need to inspect or clean up your JSON first? Open it in the JSON Viewer, then send it here with one click.
