What this tool can do today
UTF-8 encoded CSV or TSV is expected; legacy encodings such as Big5 may not be detected correctly. The delimiter (comma, tab, or semicolon) is auto-detected conservatively from the first line. Very large tables are truncated with a visible note rather than silently cut off. Because Markdown table syntax adds characters, the estimated token count can increase rather than decrease for some files — the value is a clean, AI-readable table, not a guaranteed reduction.
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 single clean Markdown table with your data, plus a metadata block showing estimated original tokens, estimated output tokens, and the token reduction percentage — which can be negative for smaller files.
Do you convert other file types?
Yes. PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), HTML, and plain text are all supported on the document converter. This page focuses on CSV/TSV; use the document converter for anything else.
