FAQ
Q1: What SQL syntax is supported?
Based on the AlaSQL engine, it supports SELECT, WHERE, ORDER BY, GROUP BY, HAVING, JOIN, UNION, DISTINCT, LIMIT, OFFSET, aggregate functions (COUNT/SUM/AVG/MIN/MAX), string functions, date functions, and more standard SQL syntax. The table name is always csvdata.
Q2: Is my data uploaded to a server?
No! All data processing happens locally in your browser using the AlaSQL JavaScript engine. Data is never uploaded to any server, ensuring privacy and security.
Q3: How large a CSV file can I use?
We recommend CSV files under 10MB (approximately 100,000 rows). Larger files may cause browser memory issues or slow queries. For large datasets, filter first or use LIMIT to restrict result rows.
