Convert SYLK to Markdown.
Drop a SYLK (.slk) spreadsheet and read its cells as a clean Markdown table. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files
or
Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Coordinates in,
a grid out.
A SYLK file stores every cell as a coordinate record with a value, not a grid you can read. The converter walks those records and rebuilds them into a tidy Markdown table.
ID;PWXL;N;E
C;Y1;X1;K"Name"
C;Y1;X2;K"City"
C;Y2;X1;K"Ada"
C;Y2;X2;K"London"
| Name | City |
| --- | --- |
| Ada | London |
Everything you
actually need.
Legacy spreadsheet records in, a clean Markdown table out, with no server and no account anywhere.
It never leaves your browser
The SYLK file is parsed and rebuilt on your own device. Nothing is uploaded to any server, ever.

AI & RAG ready
Optional cleanup, YAML front matter, a table of contents and RAG chunk export.
Works offline
Once the page has loaded you can switch off your connection and it keeps converting.
Old format, new table
SYLK predates modern spreadsheets; its C-records are parsed and rebuilt into clean Markdown you can actually read.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.
Old records,
new table.
Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for SYLK, so the page never drifts from what the converter really does.
Kept
3- Cell values
- Every cell
- Row & column order
Dropped
3- Formatting
- Formulas
- Number formats
SYLK questions,
answered.
Everything worth knowing before you drop in a .slk file.
