Online CSV to JSON & SQL Query Converter
Transform spreadsheet exports, tabular data, and raw CSV files into structured JSON objects or database-ready SQL INSERT queries. Features RFC 4180 compliant quoting, automatic delimiter detection, intelligent type inference (numbers, booleans, nulls), and zero server upload.

Escaped Double Quotes ("")
Cells containing quotes (such as "John ""Doc"" Doe") are parsed accurately according to RFC 4180 specification without breaking column alignment.
Multiline Cells with Embedded Newlines
When a quoted cell contains newlines, the parser preserves the multi-line content inside the cell rather than treating it as a new record row.
Leading Zeros Preservation
Identifiers, postal codes, and phone numbers starting with 0 (e.g. "01234") are preserved as strings to prevent data truncation.
#Frequently Asked Questions
Q:Is my CSV data uploaded to any server?
No. Parsing, type inference, and transformation occur 100% locally in your browser memory. No data is sent over the network.
Q:Can I generate batch INSERT statements for large tables?
Yes. In SQL mode, you can toggle between a single multi-row VALUES batch query or individual INSERT statements for each record row.
