Query your spreadsheet export with SQL
A CSV is fine until you need to join it, group it, or ask it a question. Loading one into a database is normally a chore involving an import wizard that guesses your types wrongly and mangles anything that looks like a number. This converter does the guessing carefully instead: it reads each column as a whole before deciding what it is, so identifiers keep their leading zeros and prices stay comparable.
- Real column types — INTEGER, REAL, NUMERIC or TEXT, chosen per column
- Leading zeros and phone numbers preserved as text, not silently rewritten
- Empty cells become NULL, and blank trailing rows are dropped
- Built in memory with quoted identifiers and bound values — nothing from the file is executed
Need to go the other way? SQLite to CSV exports every table in a database back out again.
About Converting CSV to SQLite
CSV is a plain-text table format where each line is a row and commas separate columns. Its simplicity makes it the universal exchange format for data between spreadsheets, databases and code. When you need to move away from CSV, the usual reason is simple: no formatting, formulas or multiple sheets.
Converting your CSV spreadsheet to SQLite solves that. SQLite is a complete relational database held in a single file, with the whole engine embedded in the program that opens it — there is no server to install or run. It is the most widely deployed database in the world, sitting inside phones, browsers and desktop applications, and it is a recognised long-term archival format. In practice you gain a whole database, indexes and all, in one portable file and queryable with ordinary sql, including joins and aggregates. PrivConvert runs the whole CSV-to-SQLite conversion in server memory and deletes your file the instant the SQLite is ready — nothing is stored, logged or reused.
