Does the output include inline CSS for styling?

No. The output is plain, semantic HTML without inline styles — just , , , , , and . Apply your own CSS to control the appearance.

Are special characters in cell values escaped?

Yes. Every cell value is HTML-escaped so that , &, and " appear as text rather than being interpreted as HTML markup.

Does the tool add scope='col' for accessibility?

Yes. When 'Add scope="col"' is toggled on (the default), every in the header row gets scope='col', which is a WCAG 2.1 requirement for accessible table navigation by screen readers.

Is my data uploaded anywhere?

No. All parsing and table generation run in your browser using PapaParse; the input is never transmitted or stored.

About

Generate a clean, semantic HTML table from CSV (or any delimited) data. Optionally treat the first row as a header and emit accessible scope="col" attributes on the header cells. Cells are HTML-escaped and a live preview is rendered. Everything runs in your browser; nothing is uploaded.

About this tool

Generate a clean semantic HTML table from CSV data. Optional header row and accessible scope attributes. Live preview. Free, client-side, no signup. HTML Table Generator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

HTML Table Generator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.

2D Fluid Dynamics & Particle Physics Sandbox

A physics playground with two engines sharing one canvas. The fluid mode runs a real Eulerian Navier-Stokes solver — semi-Lagrangian advection, explicit diffusion, Jacobi pressure projection and vorticity confinement — that you paint with dye and velocity using mouse or touch. The particle mode is a damped Verlet N-body engine with gravity wells, Coulomb attractors and repulsors, spring links, wall restitution and elastic circle collisions. Particle counts adapt to the device (100k target on WebGL2 desktop, 2k-5k on CPU fallback), and every configuration exports as runnable code: a Matter.js world, a PixiJS ticker setup, or a standalone vanilla Canvas engine.

Algorithm Arena & Data Structure Visualizer

Interactive arena for algorithms and data structures: eight sorting algorithms racing on one seeded input, six pathfinding algorithms walking generated mazes, and BST, AVL, Red-Black, B-tree, heap and trie operations replayed step by step with rotations highlighted. Every run shows the Big-O table and the phase-highlighted reference implementation in four languages, and compared values can be played as pitch (sonification) through the shared audio engine. Everything runs client-side; inputs never leave the browser.
