No. Everything runs in your browser - your file never leaves your device. How this is verifiable
Markdown tables are everywhere in GitHub, GitLab, wikis and documentation - but typing them by hand, with all the pipes and the separator row, is tedious and error-prone. This tool takes your CSV file (or TSV) and produces a ready-made Markdown table in GitHub format that you can paste straight into a README, an issue, a wiki or a note.
By default the first row is used as the table header; a toggle turns that off if your file has no headings - then neutral column names (A, B, C ...) are generated, because a Markdown table always needs a header row. The delimiter (comma, semicolon or tab) is detected automatically, cells containing pipes are correctly escaped with a backslash, and line breaks inside a cell become spaces so the table stays valid. Rows of differing length are padded to the widest one.
Everything runs entirely locally in the browser - your data never leaves your device, which for tables with names, numbers or internal lists is exactly the point. Honestly framed: a flat GitHub-flavoured Markdown table is produced. Merged cells, multiple header rows, formulas or formatting from a spreadsheet are not part of the Markdown table format and are therefore not represented - for such cases a real spreadsheet file is more suitable.

Limitations: Converts CSV/TSV into a GitHub-flavoured Markdown table (pipe table). The delimiter is detected automatically; pipes inside cells are escaped, line breaks inside cells become spaces. First row as header (can be turned off -> neutral columns A/B/C). Flat tables only: merged cells, multiple header rows, formulas or formatting do not exist in the Markdown table format.
For pasting tabular data into GitHub READMEs, issues, wikis, pull requests or note apps that understand Markdown.
Turn off the header toggle; then neutral columns (A, B, C ...) are generated, since a Markdown table always needs a header row.
Yes, comma, semicolon and tab are detected automatically (CSV and TSV).
They are escaped with a backslash so the table structure stays valid.
No, the conversion happens entirely locally in the browser; the data never leaves your device.
