Frequently Asked Questions
How does CSV to HTML conversion work?
The tool parses comma-separated values (CSV) line-by-line, splitting each row by commas into cells. First row becomes <thead> if 'header' is enabled; remaining rows populate <tbody>. Inline styles add borders, padding, and background colors for immediate use without external CSS.
What if my CSV has commas in values?
Standard CSV escapes commas by wrapping values in quotes (e.g., "New York, NY"). Our basic parser splits by commas—for complex CSVs with quotes/escapes, pre-process with Excel or use libraries like PapaParse. Simple data (no embedded commas) works perfectly.
Can I customize the table styles?
Yes! Toggle 'Add inline styles' for basic borders/padding, or disable for clean HTML and add your own CSS classes. The generated <table> tag accepts custom attributes—edit the output to add class="my-table" or id for external stylesheets.
Does it handle large CSV files?
Browser-based processing handles ~10,000 rows smoothly. For massive datasets (100k+ rows), consider server-side tools or splitting files. The preview renders all rows, so very large tables may slow rendering—use download for big outputs.
What's the difference between header on/off?
Header ON: first row becomes <th> tags in <thead> (bold, gray background). Header OFF: all rows are <td> in <tbody> (uniform styling). Use header for data with column names; disable for uniform grids or pre-formatted data.
Can I use this for WordPress or Blogger?
Absolutely! Copy the HTML output and paste into the HTML editor (not visual editor) of WordPress, Blogger, or any CMS. Inline styles ensure it displays correctly without theme conflicts. For responsive tables, wrap in <div style="overflow-x:auto">.
