A workbook is already a database — this makes it one
Multi-sheet workbooks are where spreadsheets stop being convenient. The tabs are related, the lookups between them are fragile, and answering anything across them means another layer of formulas. Exporting to CSV does not help, because a CSV holds one sheet and forgets the rest. Converting the workbook to SQLite keeps every sheet as a table, so the relationships you were faking with VLOOKUP become an ordinary join.
- One table per sheet, named after the sheet — nothing left behind
- Formula cells export their calculated value, not the formula text
- Dates arrive as ISO text that SQLite's date functions understand
- Parsed as data: no formula is evaluated and no macro can run
Only need one sheet as a flat file? Excel to CSV exports the active sheet instead.
About Converting XLSX to SQLite
XLSX is the modern Microsoft Excel format — a ZIP of XML that stores multiple sheets, formulas, charts and formatting. It is the standard for business spreadsheets. When you need to move away from XLSX, the usual reason is simple: needs spreadsheet software to open.
Converting your XLSX 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 XLSX-to-SQLite conversion in server memory and deletes your file the instant the SQLite is ready — nothing is stored, logged or reused.
When this conversion helps
- You need a whole database, indexes and all, in one portable file
- You need queryable with ordinary SQL, including joins and aggregates
- You need no server, driver or import step to set up
- You need stores real types, so numbers sort and compare as numbers
- Sharing a XLSX spreadsheet with someone whose software expects SQLite
