Add your XLTX file
Drop one or more .xltx files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .xltx file to .tsv extracts the document's content from its office package into a portable form. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .xltx file to .tsv extracts the document's content from its office package into a portable form. An .xltx file is a Microsoft Excel template: a workbook package marked as a starting point, so opening it creates a new unsaved workbook carrying its sheets, formulas, styles, and print setup. It is the macro-free half of the template pair.
A .tsv file stores a table as plain text with one record per line and a tab character between columns. It is CSV's stricter sibling: because literal tabs almost never occur inside data, most TSV files need no quoting rules at all. For this route the practical draw is trivially parseable — split each line on tab, no state machine required and pastes directly into and out of Excel and Google Sheets, because spreadsheet clipboards already speak tabs — balanced against a single stray tab inside a value silently shifts every following column, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .xltx, cached formula results can be stale relative to the formulas beside them. Switching to .tsv buys you trivially parseable — split each line on tab, no state machine required, which is why it is the better fit for database dumps — PostgreSQL's COPY and MySQL's SELECT INTO OUTFILE default to tabs. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | Excel template (.xltx) | TSV table (.tsv) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | package layout is identical to .xlsx: xl/workbook.xml, xl/worksheets/sheetN.xml, shared strings, and styles in a ZIP | one record per newline-terminated line, with fields split on the tab character (U+0009) |
| Strongest at | standard invoice, budget, and expense-report starting points | database dumps — PostgreSQL's COPY and MySQL's SELECT INTO OUTFILE default to tabs |
| Weak spot | cached formula results can be stale relative to the formulas beside them | a single stray tab inside a value silently shifts every following column |

Select .tsv in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TSV is selectable, the route is real and validated.
Press Convert. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TSV file. Outputs keep the original filename with the .tsv extension.
There is no visual quality to lose — xltx is text-oriented and tsv is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Yes — the .xltx file is processed inside your browser tab and never uploaded. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded. Close the tab and the file is gone from memory.
Every spreadsheet application imports TSV, command-line tools handle it natively, and any text editor opens it — though column alignment on screen can be misleading. Browsers treat it as downloadable plain text.
It depends on the content: one record per newline-terminated line, with fields split on the tab character (U+0009). Convert one representative file first and compare before batch-processing a large set.
In .xltx, carries the standard docProps core and app parts, usually naming the template's author rather than whoever later fills it in. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
