Frequently Asked Questions

RividTech is a free data operations toolkit. Its tools convert, clean, query, and preview tabular data - CSV, TSV, JSON, Excel, and SQL - entirely in your browser. It started as a small set of CSV utilities; read more about us.

No. Conversion, preview, deduplication, search, sort, and filter run locally in your browser. Your file contents are not sent to RividTech for processing. See our Privacy Policy for details.

No account or login is required, and the tools are free to use. Open a tool and start working.

Input and output formats include CSV, TSV, JSON, Excel (.xlsx), Markdown, and SQL (CREATE TABLE + INSERT). Tools that accept CSV also detect tab-separated data, so you can paste cells copied from a spreadsheet. There are also table previews, cleaning tools, and URL, HTML entity, and Base64 encoders. Each tool's page explains exactly how it handles headers, quoting, and types. Browse all tools from the home page.

You can install the site as a PWA; static pages may work offline after a first visit, but very large file processing still depends on your device memory.

Limits depend on your device and browser memory. Very large files may run slowly or fail in-browser. For huge datasets, consider desktop tools or exporting a smaller subset from the source application.

Yes. You own the data you process and may use tool output for personal or commercial projects, subject to our Terms and Conditions and any rights that apply to your original data.

Common causes include inconsistent delimiters, missing headers, quoted fields with commas, or encoding issues. Check the delimiter or load a small sample first, ensure the first row is headers when required, and check for extra blank lines.

On CSV & TSV Preview and JSON Preview, copy and download screenshot capture the full table content (not only the scrolled viewport), sized tightly to the table so small datasets do not include empty side padding. Markdown Preview renders general Markdown and lets you copy the generated HTML source.
