Why this tool is useful
Audit the structure of a downloaded application database, data export or test fixture before choosing a table to query.
Local File Tools · runs locally
Private SQLite Database Viewer
Inspect tables, column declarations and row counts from a local SQLite database without uploading the database or modifying it.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
A pinned sql.js WebAssembly build opens the selected bytes in browser memory, enables SQLite query-only mode, reads sqlite_schema and reports at most 100 user tables.
Practical example
Choose a .sqlite file and confirm that its expected tables, columns and row counts are present before importing it into another application.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
