Source format
XLSX can preserve worksheets, formulas, cell types, formatting, and charts.
XLSX
XLSX is the modern spreadsheet format of Microsoft Excel, introduced in Excel 2007. It is a compressed XML package that stores worksheets, formulas, cell types, formatting, and charts. XLSX opens in Excel, Google Sheets, LibreOffice, and Numbers.
TSV
TSV (Tab-Separated Values) is a plain-text format for tables. Each line is a row and the columns are separated by tab characters, which avoids problems with commas inside values. TSV does not store formulas, formatting, or multiple sheets.
What happens when XLSX becomes TSV
Target format
TSV stores tabular rows as tab-delimited plain text.
What changes
Records and values are parsed from XLSX and serialized using TSV syntax and data types.
- What is preserved
- Data values and record relationships are preserved where XLSX and TSV have equivalent types.
- What may be lost
- Comments, key order, formatting, formulas, styles, namespaces, or type annotations may be lost when TSV cannot represent them.
- Codec and quality implications
- This is a structural conversion rather than a visual quality setting; verify types, delimiters, encodings, and row counts in the output.
- Realistic limitations
- Malformed syntax, mixed encodings, unsupported nesting, or values outside the target type range can prevent an accurate conversion.
Conversion steps
- Upload a XLSX file no larger than 1 GB.
- Confirm that TSV is selected as the target.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the TSV file and check the result before deleting your source.
Troubleshooting
- The XLSX file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The TSV file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
