JSON to Excel Converter
JSON is the lingua franca of web APIs and modern data systems, but analysts, managers, and business users often need to explore, filter, pivot, and visualize that data in Excel. Converting JSON to Excel transforms nested, hierarchical data structures into organized spreadsheet rows and columns with proper data typing, making it immediately accessible for analysis, charting, and reporting. SublimePDF flattens nested JSON objects, handles arrays intelligently, and produces clean Excel files with formatted headers and auto-sized columns.

How to Convert JSON to Excel Online
Upload your JSON file
Drag and drop your .json file or paste raw JSON data directly. Arrays of objects, nested structures, and large datasets are all supported.
Configure spreadsheet mapping
Choose how to flatten nested objects (dot-notation keys, e.g., 'address.city'), how to handle arrays (join as comma-separated, or expand into separate rows), and select the root data path if your JSON is deeply nested.
Preview the spreadsheet layout
Review how your JSON data maps to columns and rows. Adjust column ordering, rename headers, and verify that data types (numbers, dates, text) are detected correctly.
Download your Excel file
The .xlsx file opens in Microsoft Excel, Google Sheets, or LibreOffice Calc with formatted headers, auto-sized columns, and properly typed cell data.

How to Convert PDF To Grayscale
Printing color PDFs on black-and-white printers often produces muddy, hard-to-read output because the printer's automatic color conversion isn't optimized for clarity. Pre-converting your PDF to grayscale ensures consistent, clean results on any mono printer and can dramatically reduce printing costs for large jobs. SublimePDF converts all colors—in text, images, and vector graphics—to properly weighted grayscale.
