How to Open JSON File in Excel

What this does

JSON stores records as objects with named fields, while a worksheet stores them as rows under header cells. Converting between the two means deciding which row holds the field names and how empty cells should appear (empty string vs. missing key). Excel itself has no one-click "save as JSON"; Power Query imports JSON, but exporting requires a tool or script. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “open json file in excel”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the tool above before you touch the real workbook. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. The point is a data step that keeps your analysis trustworthy, but the practical win is that someone else can open the file and understand what happened without asking you.

A worked example

A sheet has headers name and qty in row 1, with Bolt M8 / 42 in row 2 and Nut M8 / 120 in row 3. Converted with the first row as headers, the output is [{"name":"Bolt M8","qty":"42"},{"name":"Nut M8","qty":"120"}] — two records, keys taken from row 1. APIs, config files, and most web tooling speak JSON. Converting a worksheet to JSON lets spreadsheet data feed scripts and apps without manual re-typing. A practical tip before you scale it up: build it once on a small block of test data, confirm the number against the tool on this page, and only then point it at your real sheet. That one habit catches almost every mistake while it is still cheap to fix, long before a wrong figure reaches a report or a colleague.

In Google Sheets

Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. Treat “open json file in excel” as a small building block rather than a chore. Once the inputs sit in their own cells and the formula reads from them, the same setup answers a dozen related questions with a tweak, and Excel keeps every dependent figure current as the data changes. The tool above is there so you can rehearse and verify before committing anything to a real workbook; the steps and worked example are there so the logic sticks. Get it right once and it stops costing you time — it starts saving it, every time the question comes back around.

Common mistakes

• Merged header cells, which leave some columns without a key.
• Expecting Excel's Save As dialog to offer JSON — it does not; you need a converter or script.
• Forgetting that all cell values arrive as text; cast numbers in the consuming code.
• Using a sheet where the real headers start in row 3 — move them to row 1 first.
