PRIVACY

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Types are suggested from values and can be edited; incompatible numeric conversions stop the build.
Import is limited to 8 files of at most 20 MB each and 100,000 rows total; SQLite is built locally in the browser.
