How to Convert a JSON File to Excel: Step-by-Step Tutorial
📄 Open the JSON to Excel Converter and follow along with this tutorial.

Step 1: Locate Your JSON File
Find your .json file on your device. This could be an API response export, a transaction download from a payment platform, or any JSON-format data file containing an array of objects. No pre-processing is needed — the converter accepts JSON files directly and automatically unwraps common envelope patterns such as data, results, and items.
Step 2: Open the Converter
Navigate to the JSON to Excel Converter at FinancialDataTools.com. The tool loads entirely in your browser — there is no software to install and no account to create. The left panel shows the source area where your JSON data will be loaded.
Open the JSON to Excel Converter — free, private, runs in your browser.
Open Converter →Step 3: Load Your File
Click the Open button in the toolbar to open a system file picker, then select your JSON file. Alternatively, drag and drop your file directly onto the left source panel. The converter will immediately begin parsing your file.
While the file is loading, a spinner is shown in the source panel. For most files this completes in under a second.
Step 4: Review the Source Preview
Once the file loads, your JSON data is displayed as a table in the left panel. Column headers are derived from the union of all keys found across the objects in your JSON array. Numeric values are highlighted in blue. Null or missing values are shown as NULL in muted italic style.
Review the preview to confirm your data loaded correctly — check that the expected columns are present and that row counts look right. The stats bar above the panels shows total rows and columns.
For large files the preview shows the first 500 rows. A notice at the bottom of the table tells you how many rows are being previewed versus the total. The full dataset is always included in the conversion regardless of the preview cap.
Step 5: Convert to Excel
Click the Convert to Excel button in the toolbar. The converter processes all rows from your JSON file and generates the Excel output. A spinner is shown in the right panel while conversion is in progress.
The right (Excel output) panel becomes visible as soon as conversion begins.
Step 6: Inspect the Excel Output
After conversion completes, the right panel confirms the binary Excel output is ready for download. The status badge in the stats bar changes to CONVERTED to confirm the conversion succeeded. The output contains one header row and one data row per record from your source JSON array.
Step 7: Export the Excel File
Click the Export Excel button in the toolbar to download your converted file. The browser saves the file directly to your downloads folder. The output file is named to match your input — only the extension is changed to .xlsx. For example, transactions.json becomes transactions.xlsx.
The Export Excel button is disabled until a successful conversion has completed. After downloading, you can click Reset in the toolbar to clear all state and start a new conversion with a different file.
