XLTM to TSV
Converting a .xltm 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.

Converting a .xltm file to .tsv extracts the document's content from its office package into a portable form. An .xltm file is a Microsoft Excel template that is allowed to carry VBA macros, so every workbook created from it inherits both the layout and the macro project. It is the template counterpart to .xlsm.
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.
Why convert XLTM to TSV?
The practical trigger for this conversion is usually a mismatch: with .xltm, blocked by most mail gateways and by many corporate security policies. 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.
XLTM vs TSV at a glance
| Aspect | Macro-enabled Excel template (.xltm) | 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 | same package as .xltx: workbook, worksheets, shared strings, and styles in a ZIP | one record per newline-terminated line, with fields split on the tab character (U+0009) |
| Strongest at | departmental reporting templates with automated refresh or validation | database dumps — PostgreSQL's COPY and MySQL's SELECT INTO OUTFILE default to tabs |
| Weak spot | blocked by most mail gateways and by many corporate security policies | a single stray tab inside a value silently shifts every following column |
Pick TSV as the output
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.
Convert on your device
Press Convert. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded.
Verify and download
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.
XLTM to TSV questions, answered
Will converting XLTM to TSV lose quality?
There is no visual quality to lose — xltm 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.
Is it private to convert XLTM files here?
Yes — the .xltm 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.
Where will the TSV file work?
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.
Will the TSV file be bigger or smaller than my XLTM?
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.
What happens to the metadata in my XLTM file?
In .xltm, standard docProps core and app parts ride in the package and are dropped by tabular exports. 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.
