Frequently Asked Questions
Is my data safe?
Yes — DataShift runs entirely in your browser. No data is sent to any server. You can even use it offline after the page loads.

DataShift accepts an array of flat objects, e.g.,
[{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]. Nested objects will be
stringified.
What CSV delimiter is used?
Standard comma-separated values with RFC 4180 quoting rules. Fields containing commas or quotes are properly escaped.
Is there a file size limit?
No hard limit — it depends on your browser's memory. Typically handles files up to 50MB+ without issues.
