Open your workbook or data file
Select an Excel workbook in XLSX or XLS format, or choose a CSV or TSV export. Multiple sheets are supported, so there is no need to combine separate regional or planning tabs into one manually assembled input.
Convert a workbook or delimited file into Markdown tables while keeping worksheet names and empty cells.
Drag and drop your files, or choose them from your device.

Excel, CSV and TSV file conversion runs in your browser; spreadsheet contents are not uploaded for parsing.

Use the live Markdown editor to inspect each named sheet section and its GFM preview. Check the LLM token count as you remove irrelevant worksheets or explain abbreviated headers, keeping the financial values associated with the correct reporting period.
Download the Markdown file or copy an individual table into GitHub, Obsidian or an AI prompt. Parsing happens on your device, and you can erase optional recent-output history from the current tab when the review is finished.
For a multi-sheet workbook, each worksheet receives a named section rather than being silently combined with unrelated tabs. This makes a revenue report and a growth plan distinguishable in one Markdown document, while preserving the order used in the workbook for a straightforward side-by-side review.
Displayed spreadsheet values take priority over executable formulas. Currency, percentage and date formatting help readers interpret the exported table, but a Markdown copy cannot retain workbook calculation behavior or update dependent totals after you edit a source figure.
Blank cells inside the used data area remain in their column positions. This prevents an absent forecast, optional note or intentionally empty comparison period from pulling later values left and making a row appear to support a different interpretation.
Comma-separated and tab-separated files share the same table-focused workflow. Quoted separators and multiline fields are read as cell content, while international characters remain Unicode text; look carefully at exports from older systems that use an unexpected separator or encoding.
A workbook often encodes context outside the visible numbers: sheet names identify time periods, captions describe units and empty rows divide groups. Markdown gives you a portable view of the content, not a replica of the spreadsheet interface. Before sending a table to colleagues, add a brief explanation of its units and whether totals are rounded. Retain the original workbook whenever another person may need to audit formulas, filters or a chart’s underlying range.
For AI analysis, choose the smallest relevant range and give every field an informative header. A clean pipe table usually communicates tabular relationships better than a screenshot, and the token counter helps you decide whether to include detailed rows or an approved summary. It remains your decision which evidence belongs in the prompt: the converter neither validates a forecast nor supplies missing business facts. Sensitive customer records should be removed before sharing the Markdown with another service.
Markdown receives cell values, not functioning spreadsheet formulas. Where a workbook supplies a saved result and number format, that display is used; the converter does not recalculate the workbook. Save a freshly calculated copy in your spreadsheet application before uploading if formulas have changed. Keep the XLSX original for anyone who needs to inspect dependencies, change assumptions or reproduce the calculation behind a total.
Each worksheet becomes its own section headed with ## Sheet: followed by the sheet name. The table below that heading contains that worksheet’s used rows and columns, and the next sheet begins a separate section. You can delete a section that is irrelevant to your report without affecting other sheets, or rename a heading in the editor to explain an abbreviated tab name.
An amount displayed as ₹14,85,000 can keep both its rupee symbol and Indian digit grouping, while values using international groupings remain in their displayed form. CSV and TSV inputs preserve their textual figures rather than adopting a new locale. Confirm the source cells use the intended format, especially if an amount is stored as a bare number with the currency described only in a neighboring note.
An empty interior cell still identifies a place in the row. Removing it would shift every following value under the wrong heading, turning a missing figure into a misleading comparison. The Markdown table therefore includes an empty field between pipe separators. If a blank means zero, unavailable or not applicable, explain that distinction in a note instead of asking the converter to infer the intended meaning.
