CSV to SQLITE Converter
Processing entirely on your device — large files may take a moment.
CSV (Comma-Separated Values) is the universal spreadsheet export format: one table of rows and columns stored as plain text, opened by Excel, Google Sheets and every data tool. Dump SQLite tables to CSV/JSON to explore app data without installing anything.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How CSV compares to SQLITE
| CSV | SQLITE | |
|---|---|---|
| Structure | One flat table | Pages, tables, indexes |
| Types / schema | Untyped (all strings) | SQL column types |
| Compatibility | Excel, Sheets, databases, code | Every OS, every language |
| Best for | Data exchange and bulk import | App data and embedded storage |

About the CSV format
CSV (comma-separated values) is the lowest common denominator of tabular data: one table, rows as lines, columns separated by commas, everything plain text. Excel, Google Sheets, every database importer, every data-science library and every scripting language read it, which is why it has survived fifty years of format fashion.
Its weaknesses come from the same minimalism. There are no types (everything is a string until you decide otherwise), no formulas, one table per file, and dialect quirks are legendary: comma vs semicolon locales, quoting rules, and Excel's insistence on re-opening UTF-8 files without a BOM as mojibake. Clean, well-formed UTF-8 CSV with a BOM sidesteps nearly all of it.
+ Strengths
- ✓Universal: Excel, Sheets, databases and code all read it
- ✓Human-readable and diff-friendly
- ✓Streams well — process giant files line by line
! Limitations
- −No types, no formulas, no multiple sheets
- −Dialect chaos: delimiters, quoting, encoding
- −Nested or hierarchical data does not fit
About the SQLITE format
SQLite is the most deployed database engine on earth — a single cross-platform file holding real tables, indexes and queries. App state, browser caches, game saves and downloaded datasets frequently arrive as a .db/.sqlite file, and the whole database is just sitting there.
Dumping its tables to CSV or JSON turns an opaque binary into rows you can open anywhere — the fastest way to answer “what does this app actually store?”
+ Strengths
- ✓Real SQL database in one file
- ✓Zero-configuration and everywhere
- ✓Tables, indexes and types included
! Limitations
- −Binary — needs a reader to open
- −Schema quality varies by app
Why convert CSV to SQLITE?
There is a concrete reason this conversion exists: No types, no formulas, no multiple sheets SQLITE sidesteps that — Real SQL database in one file If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this CSV to SQLITE converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
What about special characters and non-English text?
Everything is handled as UTF-8. When you export CSV for Excel, a UTF-8 BOM is included automatically so Chinese, Japanese, Korean and accented characters display correctly on both Windows and macOS.
Is my data safe here?
Yes. The conversion is plain JavaScript running in your tab: the data is parsed and re-serialized in memory, never sent anywhere, and disappears when you close the page.
Are formulas, styles or multiple sheets converted?
No — this conversion extracts the data itself into SQLITE. Formulas are exported as their current values, styling is not carried over, and multi-sheet workbooks convert sheet by sheet. For full fidelity between spreadsheet formats, exchange within the same tool family.
