About JSON to XLSX conversion
JSON is a text-based key-value data interchange format compliant with the RFC 8259 standard. It only supports six basic data types and does not natively support table structures. XLSX is a ZIP-compressed XML spreadsheet format compliant with the ISO 29500 standard, which supports structured table storage. This creates demand for converting structured JSON data to XLSX spreadsheets.
This conversion is completed based on the SheetJS engine. JSON array objects are converted to XLSX table rows, object properties are converted to the header row, all original key names and corresponding values are retained, and cell data types are automatically inferred. A single JSON input outputs a single XLSX worksheet, and the output file size complies with ZIP compression rules.
This conversion is suitable for workflows that require importing JSON data returned by APIs into Excel for statistical analysis. The output XLSX is compatible with Excel 2007 and later versions, and can be opened and used in mainstream spreadsheet software on Windows and macOS systems.

FAQ about JSON → XLSX
Will data be distorted after conversion?
Text and numeric data contained in the original JSON are fully retained. Boolean and null types are converted to corresponding XLSX text values. Date types not supported by JSON do not generate additional redundant data, and there is no uncontrolled data distortion.
Do you support retaining JSON hierarchical structure?
The current conversion only processes first-level JSON array structures. Nested hierarchical structures are flattened into peer cell content. JSON with a non-array top level is converted into a single-row key-value pair table.
What is the single file size limit?
The maximum single file size accepted by the conversion service on this site is 50MB, and only one file can be converted at a time. Nested JSON files that comply with compressed package security rules can be processed normally.
Will my files be stored?
Files are uploaded to the server via HTTPS for conversion. After conversion is complete, the server immediately deletes both the source file and the output file, does not store any files, and retains no user data.
