AROTIP // Free Tools
Five tools. No signup.
Working tools, not lead magnets. Four of the five process everything on your own machine — your file never touches a server. The fifth says so, plainly, right on its badge.

Questions, answered plainly
No fine printAre these tools really free?
Yes — every tool on this page is free, with no trial period and no paywall. They're how we demonstrate the kind of work we do; our paid business is data services, not tools.
Does my data leave my browser?
Four of the five tools — the Data Validator, Data Deduplicator, CSV↔JSON Converter, and Data Anonymizer — process everything in your browser. Your file never touches a server. The one exception is the Dashboard Generator, which uploads your file to our server to build the dashboard; the file and the dashboard are automatically deleted after the dashboard expires.
What are the file size and usage limits?
Files up to 5 MB, and each tool allows 5 uses per hour. That covers normal use comfortably. If you regularly hit either limit, you probably have a services-sized problem — contact us.
Do I need to create an account?
No. There is no account system — nothing to sign up for and no login. The Dashboard Generator asks for an email address only so it can send you the dashboard link.
Can I use these tools for commercial purposes?
Yes. Use the output however you like, personal or commercial — no restrictions and no attribution required.
I need a custom data tool. Can you help?
Probably. Building custom data transformation tools and pipelines is exactly what we do. Contact us with your requirements and we'll tell you what it would take.
Beyond the free tools
Need more than a 5 MB fix?
The tools handle files. We handle the pipeline — cleaning, enrichment, migration, and dashboards that stay current. Start with a free data audit.
