CSV to JSON
Leading zeros are identifiers, long digit strings lose precision as numbers, and 03/04/2026 has two readings. This infers types and knows where to stop.
Developer💻JSON Escape
Seven characters become eleven, then nineteen. By the third level nobody can edit it by hand — which is the signal to stop nesting.
Developer💻JSON Formatter
Paste broken JSON and get the exact line and column that failed, with a human explanation of what the parser expected. Format, minify, sort keys and copy out.
Developer💻JSON Key Sorter
Key order means nothing to a parser and everything to git. Sorting recursively turns a reshuffled file back into a one-line diff.
Developer💻JSON Minifier
Minifying cuts a third of the raw bytes and almost none after gzip, because whitespace compresses away. This measures both, so you know if it is worth doing.
Developer💻JSON Size Analyzer
Total size says there is a problem. Per-key size says which one, and the answer is rarely distributed evenly.
Developer💻JSON to CSV
Nested objects become dotted columns. Arrays have no right answer, so you get both options and what each one loses. Quoting is handled properly.
Developer💻JSON to Go Struct
Go has no undefined, so a missing number and a zero look identical after Unmarshal. This generates the tags, exports every field, and says where a pointer is needed.
Developer💻JSON to TypeScript
A missing key and a null key are different types. Most generators emit any for both. This merges every array element first, then explains each decision.
