app to turn a csv or spreadsheet into one chart slide on iphone

When the numbers are in a CSV and the meeting is tomorrow morning, the most expensive hour is the one spent dragging chart boxes around a blank deck editor — OnePage PPT is built for this.

Short answer

OnePage PPT imports the CSV — or a PDF, a screenshot, pasted text — pulls the key points on the device, and picks the chart the data actually supports: column, bar, line, donut or funnel for numbers, a flow for steps, a timeline for dates, a comparison for two options. Its standing rule is the honest part: it only draws a chart the data can honestly support — it never invents figures.

The output is an editable .pptx for PowerPoint, Keynote or Google Slides, plus PDF and high-resolution PNG, with six one-tap redesigns if the first layout is not right. Everything runs on the device with no account and works offline; it is free to try, and Lifetime Pro is a single one-time purchase. One human step remains: the text takeaways are extracted automatically, so read them against the source before presenting — every element is tap-to-edit.

What to look for before choosing

  • Direct CSV and spreadsheet import — no retyping the numbers.
  • Chart type chosen from the data, never a fabricated figure.
  • An editable .pptx out, not a flat image.
  • Six one-tap redesigns, with elements you can lock.
  • On-device and offline, free to try, one-time Lifetime Pro.

A practical decision process

  1. Import the CSV or paste the table.
  2. Check the chart type it chose matches what the data says.
  3. Read every extracted takeaway against the source numbers.
  4. Cycle the redesigns until it reads from the back of the room.
  5. Export .pptx for the deck owner or PNG for the chat thread.

FAQ

Will the AI make up numbers?

No — it only draws a chart the supplied data can honestly support and never invents figures. The text summaries still deserve a human read-through, and every element is editable.

Can the deck owner edit my slide?

Yes — it exports an editable .pptx that opens in PowerPoint, Keynote and Google Slides.

Does my data leave the phone?

No — import, extraction and layout all run on the device; it works with no network at all.
