JSON to Excel Converter

This tool converts JSON payloads into structured Excel workbooks. It accepts arrays of objects and nested objects, turning each object into a row and each field into a column. When fields are nested, you can opt to flatten them so nested keys become column names. If you disable flattening, nested objects are serialized as JSON strings in a single column.
The parser reads the JSON, resolves the schema across all rows by collecting keys, and builds a tabular representation. Type inference assigns numeric, boolean, and date types where possible; strings remain text. The output is an XLSX file with optional headers and a count of rows.
Who benefits: data engineers, analysts, and teams integrating JSON feeds into spreadsheets or reporting dashboards. Unique value: deterministic, repeatable exports with optional flattening, depth control, and data validation to catch anomalies before export. Core features include flatten nested structures, control depth, include or omit headers, specify sheet names, and validate data. Use cases include API data exports, log sampling, configuration dumps, and ETL testing. The tool emphasizes reliability and predictable output for downstream analytics.
