Questions

Everything you wanted to ask

Quick answers about the tools in this category — what they cost, what they need and how they work.

Still have a question? We usually reply within one working day.

Which formatters are here?
The everyday ones. There is an AI JSON Formatter, an AI SQL Formatter, an AI XML Formatter, an AI YAML Formatter and an AI CSV Formatter, plus an AI Data Structure Formatter for the nested shapes that fit none of those.

Can I tidy a minified JSON payload?
Yes. Paste it into the AI JSON Formatter and it comes back indented with the nesting visible, which makes a bug far easier to see. Run the AI Data Cleaner first if the payload arrived with stray characters attached.

Is there something for test data?
The AI CSV Generator builds rows to a shape you describe, which beats typing fake records by hand. The AI URL Generator does the same for links, including the query strings you want when testing how a page reads parameters.

What does the data standardizer do?
The AI Data Standardizer makes a set agree with itself. Dates end up in one format, names follow one casing rule and units stop switching halfway down the file, which is usually what breaks an import somewhere else.

Can I make a QR code here?
The AI QR Code Utility turns a link or a short piece of text into a code you can print or drop into a design. The AI Barcode Utility covers product codes when a label or a stock sheet needs one.

Does my SQL stay valid after formatting?
The AI SQL Formatter only changes spacing, casing and line breaks so a long query becomes readable. The statement itself is untouched, so what you paste back into your editor runs exactly the way it did before.

Is any of this paid or limited?
No. Every utility here is free with no cost and no trial, and no account or sign up is needed because they run as guest tools in the browser. Everything works on phones, tablets and desktops with nothing to install.
