CSV → JSON
The NexVaani CSV to JSON Converter transforms tabular CSV files, Excel exports, and spreadsheet data into structured, formatted JSON objects and arrays. Ideal for data scientists, developers migrating databases, and analysts formatting records for API endpoints. It features automatic type inference (converting numeric strings to numbers and true/false to booleans) with browser-based local processing.

기술 아키텍처 및 실행 방식
RFC 4180 CSV Grammar & Delimiter Tokenization
The conversion algorithm parses input against RFC 4180 rules, handling quoted fields with embedded commas and newline characters. Headers are tokenized as JSON object keys, and subsequent data rows are mapped to corresponding key-value pairs in O(N) complexity.
JSON_Array = Rows.map(row => Object.fromEntries(Headers.map((h, i) => [h, ParseType(row[i])])))기술적 제한 및 운영상의 제약
- CSV files without a header row will default to generic column keys (col1, col2, col3).
- Malformed rows with mismatched column counts will be flagged or padded with null values.

자주 묻는 질문과 답변
How does the converter handle commas inside quoted spreadsheet text?
Our parser follows RFC 4180 standards, properly recognizing quotes so that text like "New York, USA" is kept as a single value rather than split.
Does this converter automatically detect numbers and booleans?
Yes! Numerical values are converted to JSON numbers and true/false strings are converted to native booleans.
Are my private company spreadsheets uploaded to your servers?
No. All parsing runs 100% locally inside your web browser.
Can I convert Excel files exported as TSV (tab-separated)?
Yes! Select the Tab delimiter option to parse TSV files seamlessly.
Are my files uploaded, analyzed, or stored on NexVaani servers?
Where supported, tool inputs and files are processed locally inside your web browser using WebAssembly and HTML5 Canvas. Your files are not uploaded to NexVaani file-processing servers.
