Use this converter when the source value, representation, or measurement unit is known and you need the equivalent value in a supported target form without changing its underlying meaning.

JSON

Required string input.

Column names for array rows

Optional list input.

Convert a JSON array of records or equal-length arrays into canonical tool.io TableData, preserving nested JSON values and inferring column types. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Table

The resulting table returned as an object.

• A conversion is only valid when the input convention is identified correctly. Unit systems, character encodings, byte order, color profiles, reference conditions, rounding, and calendar or time-zone rules can make superficially similar values non-equivalent.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Keep the original value and its unit or encoding alongside the result. For interchange, also validate the output against the receiving format, standard, color profile, or reference conditions.

• Markdown to Table
