Type your analysis notes in Markdown and preview the rendered output before you paste them into the wiki.
The tools that come up when the actual job is interpreting data rather than collecting it: CSV viewer with column typing for the export you just got from the database, JSON formatter for the API response, regex tester against the source string, base64 for the binary blob someone embedded in a JSON field, hash for source verification, and the AI summarizer for digesting long-form sources.
Treat the preview as a scratch pad and keep the master copy in your own editor or repository. The preview is there to check structure before the text goes anywhere else.
A Markdown table needs the header row, a separator row of dashes, and the same number of pipes on every line. One missing separator collapses the whole block into an ordinary paragraph.
Fine for drafting and structure checks. For anything published, keep the Markdown in your repository and let your own toolchain render it, so what you reviewed is exactly what ships.
