Why PixNudge
Nothing is uploaded
Your data is processed in your browser and never sent to a server, so API keys, tokens and customer data stay private.
Instant, even for large files
There is no round trip to a server: results appear as you type, and files of several megabytes are handled smoothly.
Exact numbers
Long numbers such as 64-bit IDs are kept exactly as written instead of being rounded.
Frequently asked questions
How is JSON turned into a spreadsheet?
An array of objects becomes a table: each object is a row and each key is a column. If the top level is an object whose values are arrays, each array becomes its own sheet, named after its key.
Which files can I convert to JSON?
Excel workbooks (.xlsx, .xlsm, .xlsb and .xls), OpenDocument spreadsheets (.ods) and CSV files. Choose one sheet or All sheets. Dates are written as text such as 2026-10-01.
Is my spreadsheet uploaded?
No. The file is read and written in your browser, so spreadsheets with customer or financial data never leave your device.
