Chuyển đổi phản hồi API phức tạp hoặc xuất JSON thành bảng sạch và có thể sắp xếp. Flattening tự động với ký hiệu chấm + xuất CSV/Excel bằng một cú nhấp chuột.
Modern APIs and databases like MongoDB or Firebase export data in JSON format. While powerful, JSON's nested structures make it impossible to use in standard spreadsheets like Excel or Google Sheets. Our tool acts as the ultimate bridge by providing one-click dot-notation flattening.
Instead of simple top-level extraction, we dive deep. A nested address becomes
user.location.city, ensuring zero data loss during conversion.
Our generator handles commas, quotes, and multi-line strings according to RFC 4180 specs, ensuring your Excel files open without formatting errors.
Your data stays in your RAM. No server uploads, no logs, no risks. 100% client-side processing for high-security environments.
Dot-notation (e.g., purchases.0.price) is the industry standard for mapping semi-structured
data to relational tables. It allows Data Analysts to maintain the hierarchy of the original JSON while
working in a flat CSV environment.
Our tool can handle files up to 50MB directly in the browser. For larger files, we recommend splitting them into chunks to prevent browser memory crashes.
If one object in your JSON array has a field that another lacks, our Schema Detective automatically inserts "N/A" or empty values, so your CSV columns always align perfectly.
Paste your JSON data into the input area and click Convert. The tool automatically flattens nested objects and arrays into clean CSV columns.
Yes! The tool uses smart flattening to convert deeply nested JSON objects into flat CSV rows, preserving all data with dot-notation headers.
No. The conversion runs entirely in your browser, so there are no server-side limits. Handle files of any size.
