What this tool can do today

Each worksheet becomes a Markdown table, with shared strings, dates, and booleans resolved correctly. Formulas are never recalculated — the cached value stored in the file is used when available, and disclosed honestly when it is not. Charts, pivot tables, and merged-cell layouts are not fully reconstructed. Very large or overly complex workbooks fail clearly with an explanation instead of getting stuck in processing. Because Markdown table syntax adds characters, the estimated token count can increase rather than decrease for some spreadsheets — the value is clean, reviewable structure, not a guaranteed reduction.

A measured Excel example where tokens increase

quarterly-sales.xlsx-100%

Extracted cell text · 15 estimated tokens

Quarterly sales
Region Revenue
Taipei 1234
Kaohsiung 987

Reviewable Markdown · 30 estimated tokens

## Quarterly sales

| Region | Revenue |
| --- | --- |
| Taipei | 1234 |
| Kaohsiung | 987 |

Measured synthetic fixture in the current XLSX pipeline: one heading, one table, and three rows were emitted. The signed reduction is -100% because the estimate rose from 15 to 30 tokens. The added heading, pipes, and separator row are observable output structure; this example does not claim that every workbook changes by the same amount.

File retention

Uploaded originals and conversion results are temporary. They are not kept as a permanent document library.

  • Uploaded originals are used only to produce your Markdown result and are deleted as soon as processing ends, or within 60 minutes at the latest.
  • Conversion results and job records are available for up to 60 minutes, then expire and are automatically removed from the active database.
  • We do not keep a permanent document library. Limited provider-managed infrastructure snapshots may retain residual copies for up to 5 days before automatic expiry.
  • Uploaded originals are held in temporary local storage only while the job is processed. Recurring cleanup removes any expired temporary upload left by an interruption.

Frequently asked questions

What happens to my file after upload?

It is kept in temporary storage only while your job is processed, deleted immediately after processing ends, and never stored permanently. See our privacy page for the full retention policy.

What output will I get?

A Markdown table for each worksheet, with dates and cached formula results resolved where available, plus a metadata block showing estimated tokens and the signed token change — which can show an increase for spreadsheet-heavy files.

Do you convert other file types?

Yes. PDF, Word (.docx), OpenDocument Text (.odt), PowerPoint (.pptx), HTML, CSV/TSV, and plain text are all supported on the document converter. This page focuses on Excel; use the document converter for anything else.
