Usage Guide

Features

CSV Preview & Analysis tool lets you quickly view CSV data in table format, automatically count rows and columns, and infer column data types (number, date, string). It can also convert CSV data to a JSON array for easy programmatic processing and data exchange.

Steps

Paste CSV content in the "CSV Data" text area, select the delimiter (comma by default), check "First row as header" as needed. The table preview, statistics, and JSON conversion results update in real time. Click "Copy JSON" to copy the converted JSON, or click "Download CSV" to save the original data as a file.

Notes

This tool uses simple delimiter parsing and does not handle quoted fields (fields containing delimiters or line breaks). The table preview defaults to showing the first 100 rows for performance. Column type inference is based on the format of all non-empty cells in each column, with date recognition supporting common formats like YYYY-MM-DD and DD-MM-YY.
