Text & Developer Tools Frequently Asked Questions
Are my JSON API keys or CSV customer database exports uploaded anywhere?
Never. All JSON parsing, formatting, CSV tokenization, and text transformations execute in local browser JavaScript memory. Sensitive database rows and API tokens remain strictly isolated on your device.
Which casing formats are supported by the Case Converter?
The Case Converter supports 13 formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case, alternating cAsE, and InVeRsE CaSe.
Does the CSV to JSON converter handle escaped quotes and commas correctly?
Yes. The CSV parser strictly complies with the RFC 4180 standard, accurately parsing escaped quotes, custom delimiters (comma, semicolon, tab), and multi-line cell records.
How are passwords generated in the Password Generator?
Passwords are generated using the W3C Web Crypto API (window.crypto.getRandomValues). Random entropy is drawn directly from your operating system hardware CSPRNG rather than predictable Math.random().
Can the Word Counter measure reading time and paragraph counts?
Yes. In addition to word and character counts (with and without spaces), the Word Counter computes sentence counts, paragraph counts, reading time, speaking time, and reading level metrics.
