Exact Data Storage Converter
Paste JSON or load a UTF-8 document. Choose the correct formatter or converter explicitly; switching keeps your source and does not process it automatically.
Limits and accepted input
Strict JSON values, including objects, arrays, strings, zero, false and null. Empty input is invalid. Duplicate keys, unsafe integers, more than 10,000 values or more than 40 nesting levels are rejected.
Input is limited to 100,000 UTF-16 units; uploaded files to 100,000 bytes; output to 1,000,000 units. Worker deadline: five seconds. File contents must be UTF-8. A leading transport BOM follows the existing text-file decoding policy. Filename and MIME never change the selected tool; validity is checked from the contents.
Errors preserve the decoded input, clear stale output and keep export disabled. Correct the input and retry, or reset. Output and errors are plain text; no HTML, scripts, external resources or queries are executed.
Tools run locally in your browser. Original tools remain in the site catalog. Files and text are not uploaded; choose an action to format or convert.
