Clean data.
Draft documents.

Locally mask common email, credential-label, authorization-header and private-key patterns, plus exact text you specify. Review the complete output: this is not complete secret detection or anonymization.

Validate JSON Lines and convert it to a JSON array, or convert an array to one JSON value per line. Blank records, duplicate keys, unsafe numbers and malformed JSON are rejected.

Validate, format, compact, or sort JSON object keys. Duplicate keys, unsafe numbers, and excessive nesting are rejected.

Convert an array of flat objects with identical columns. Scalar values become text; null becomes the text null. Nested values are rejected. CSV formula prefixes are neutralized.

Convert comma-separated CSV with a header row. Every value stays a string, preserving leading zeros and exact decimal text. Header names are trimmed and case-sensitive.

Compare JSON values, ignoring object-key order. Arrays are compared by position. Results use JSON Pointer paths; no guessed record matching.

Encode or decode one URL component, not an entire URL. Decoding preserves + as a plus sign; malformed escapes and invalid UTF-8 are rejected.

Encode UTF-8 text or decode standard Base64 to UTF-8 text. Binary files and Base64URL are outside this tool. Encoding is not encryption.

Convert an explicitly selected Unix unit or an ISO timestamp with timezone to UTC. No local-time or seconds/milliseconds guessing.

Hash the exact UTF-8 text, including spaces and line endings, using Web Crypto. A digest does not encrypt or anonymize the original text.

Generate 1–100 UUID v4 identifiers with browser cryptographic randomness. No text input is needed.

Compare two texts with insertion and deletion markers. Line endings are normalized to LF; final-newline differences are reported. No word-level or minimal-edit claim.

Apply one explicit line cleanup. Duplicate removal keeps the first exact, case-sensitive line. All modes normalize line endings to LF.

Select and reorder existing columns by their exact, case-sensitive header names. No automatic renaming, missing-column guesses, or value conversion. CSV formula prefixes are neutralized.

Convert explicitly selected delimiters with quoted fields, embedded line breaks, and exact text values. First row is the header. No delimiter guessing or type conversion; spreadsheet formula prefixes are neutralized.

Extract one value using an explicit JSON Pointer path, such as /order/items/0/id. Empty path selects the whole document. Missing paths fail clearly; no code, filters, or wildcard expressions run.

Inspect an HTTP(S) URL or query string without opening it. Repeated parameters, order, raw encodings, and flag-versus-empty values are retained. Query + decodes to space; malformed query escapes fail clearly.
