●MidSolve My ProblemShip It

Useful for quick cleanup, but JinaAI and LLMs already handle this natively.

Strengths
  • •No sign-up requirement removes friction for one-off tasks.
  • •Specific focus on repeated patterns helps structure messy lists.
Weaknesses
  • •LLM wrappers are now native to Excel and Google Sheets.
  • •No clear advantage over just pasting text into ChatGPT directly.

Post Description

Hi HN,

I built MessyData as a small online utility for turning messy data into clean tables because I repeatedly do this.

I use ChatGPT (or other AI) to help me interpret and format data into a table. Wondered if others who don't use AI directly would need this.

And can then copy the result or download it as CSV.

It is an MVP, so I’m interested in: - What kinds of messy data people might need it to handle? - Where the output breaks or could be improved? - If CSV/table export is enough, or if XLSX/Google Sheets export would be more useful? - If it's worth expanding?

I'm also looking to give transparency that it uses AI, which I haven't done yet, if that's something that's needed for trust. Meaning, will there be people who don't care and will be glad of this tool; or will it be better to cater to those who would be more concerned. (I'm leaning towards the latter, and personally would encourage it.)

Welcoming any feedback, critique, or examples of how this could be useful.

Introspect – messy CSV exports into shareable dashboards (no signup)

Drop a messy spreadsheet in and you get two charts, a clean table, and an AI-written executive update that calls out top drivers and provides a shareable link—no signup required. It’s a neat, low-friction way to turn exports into client-ready notes quickly, but the concept is familiar and its usefulness will hinge on how reliably the model stays grounded and how it handles larger, messier datasets.
