Data Schema Analyzer
Find out what your data contains, how clean it is and how to structure it better.
Detects what your data is about, what every field means, scores data quality and recommends an optimized schema.
Automatically fixes broken CSV, malformed JSON and encoding errors, and shows every change it made.
Maps correlations, associations and dependencies between fields and groups related fields into clusters.
Generates a plain-language explanation of your dataset and its schema in any of 18 languages.
Convert many files at once, merge their schemas and download everything as one ZIP with a unified report.
Your work is versioned automatically in the background. Compare, pin or roll back to any version.
Native handling of Arabic and Urdu data: digits, separators, bidirectional marks, letter forms and right-to-left tables.

Frequently asked questions
What does this tool do?
It converts CSV to JSON and JSON to CSV instantly in your browser, and adds AI tools that repair broken files, explain your data and recommend a clean schema.
Is my data uploaded?
Basic conversion happens entirely in your browser. Data is sent to our server only when you use AI tools, version history or batch conversion, and personal data is masked before any external AI processing.
Which delimiters are supported?
Comma, semicolon, pipe, tab and the Arabic comma, with automatic detection.
How are nested JSON objects handled?
When converting to CSV, nested objects are flattened into dotted column names (for example contact.email). When converting to JSON, dotted headers can be turned back into nested objects.
Can it fix invalid JSON or broken CSV?
Yes. The repair engine fixes trailing commas, comments, single quotes, unquoted keys, missing brackets, uneven CSV rows, unclosed quotes and garbled characters, and lists every change.
Does it support Arabic and Urdu data?
Yes. It understands Arabic-Indic and Urdu digits, Arabic separators and letter forms, removes hidden direction marks and shows right-to-left tables.
