Step 1 Data ✓ Online

Parse, Clean & Transpose Messy Delimited Data

Launch CSVJSON (No Login) ↗
Input Raw Comma/Tab Delimited CSV String
Output Normalized JSON Array / Clean CSV Table

Paste your raw CSV, TSV, or spreadsheet export into CSVJSON. Select delimiters, handle quoted strings, detect column types, transpose rows into columns, or convert flat records into hierarchical JSON structures.

💡
Pro Tip: Use CSVJSON’s "Parse JSON values" toggle to parse nested JSON strings inside specific table columns automatically.

Step 2 Data

Convert to Markdown, HTML & LaTeX Formats

Launch TableConvert (No Login) ↗
Input Clean Tabular Data
Output Markdown Table / HTML Snippet / LaTeX Matrix

Load your clean tabular data into TableConvert. Format and align columns, filter rows, and generate formatted Markdown tables for GitHub READMEs, HTML `<table>` snippets, or publication-ready LaTeX tables for Overleaf research papers.

💡
Pro Tip: TableConvert features an interactive table editor where you can sort columns, edit cell values directly, and copy formatted Markdown in one click.

Render Publication-Ready Vector Visualizations

Launch RAWGraphs (No Login) ↗
Input Clean Tabular CSV / JSON Dataset
Output Publication-Grade SVG / PNG Chart

Drop your cleaned dataset into RAWGraphs. Map dimensions to visual channels and choose from advanced charts: alluvial diagrams, circular treemaps, beeswarm plots, bump charts, or convex hulls. Customize color palettes and export vector SVG or high-res PNG.

💡
Pro Tip: Export as SVG to easily adjust typography, legend placement, or color fills in vector software like SVG-Edit without rerendering.

Why This Stack Beats Cloud SaaS

Analysts and researchers frequently need to clean raw business exports, format tables for academic papers, and visualize trends for executive briefings. Uploading proprietary sales figures or user datasets to cloud dashboards risks data exfiltration. This workflow sanitizes, formats, and graphs tabular data entirely inside your browser.

Corporate analytics platforms like Tableau or PowerBI require costly subscriptions and upload company financials to cloud data warehouses. Chaining CSVJSON (in-memory parsing), TableConvert (multi-syntax conversion), and RAWGraphs (client-side D3 rendering) gives data professionals an airtight private data science bench.

Frequently Asked Questions

Does RAWGraphs upload my dataset to a remote cloud server?

No. RAWGraphs processes all data calculations and D3 vector rendering directly in your browser’s JavaScript thread. Your data never touches any external server.

Can I export charts as vector graphics for research paper publication?

Yes. RAWGraphs exports crisp vector SVG files that scale infinitely without pixelation and can be inserted into LaTeX/PDF publications.
