Everything the Excel to JSON converter handles for you
Headers become JSON keys
Every column header maps straight to an object key. The AI normalizes Client Name, client_name, and CLIENT NAME to one consistent field first, so you don't ship a payload with three spellings of the same key.
Messy values escaped safely
Quotes, commas, and line breaks buried inside a cell are escaped properly instead of breaking the payload. The output parses on the first try rather than throwing an unexpected-token error in your developer's console.
Pretty-printed and valid
You get a two-space indented JSON array that passes any linter. Paste it straight into an API request body, a config file, a Postman collection, or a seed script without reformatting it by hand.
Clean the data before you export
Garbage in, garbage JSON out. Remove duplicate rows, unify date and phone formats, and fix inconsistent casing first, so the JSON you hand over is actually usable instead of bouncing back to you.
CSV to JSON works the same way
Drop a .csv export from your CRM, database, or billing tool and convert it with the identical flow. You do not need Excel installed on your machine to convert a CSV to JSON here.
Free on every plan
JSON export is not locked behind a paywall. The Free plan gives you 5 AI runs every 20 minutes for files up to 500 rows, and the JSON download itself is unlimited and free.
Ask the AI to reshape it first
Use the AI Data Assistant to drop the three columns nobody needs or rename a field in plain English, then export. No formulas, no find-and-replace across 4,000 rows.
100% private processing
Your file is parsed locally in your browser with SheetJS and the backend is stateless. Nothing is persisted on our servers, which matters when the spreadsheet is full of client contact details.
No developer needed
Stop waiting three days for someone to write a five-line script. Convert the file yourself, send the JSON back the same hour, and close the ticket before your monthly target slips.

How It Works: Technical Methodology
Google Gemini Integration
DataSort uses Google Gemini 2.5 Flash to read the semantic meaning of your columns before serialization. That is how it knows Client Name and Customer describe the same field and unifies them into one JSON key instead of two.
Privacy & Processing
We employ a stateless architecture. Files are parsed locally in your browser using SheetJS, and only the data chunks the AI actually needs are sent to the model. No file data is permanently stored on our servers.
