A little clarity.
Simple tools. Straight answers.
Does my data leave my device?
Tool input is processed in a Web Worker in your browser. TidyFormats does not upload, store, or send your source data to an API.
Do I need an account?
No account, subscription, or sign-up is required. Open a tool and start working.
How large can my file be?
The studio accepts up to 10 MiB of UTF-8 text per operation. Processing runs in a worker, with a timeout for unusually complex documents.
Which formats are supported?
Convert between JSON and CSV or YAML, format and validate JSON, and clean CSV. CSV-to-YAML is not currently supported.
