to xlsx

Converts TSV input to Excel (.xlsx) format.

Behavior:

• Creates an Excel spreadsheet from TSV data.
• Writes all input rows into a single sheet.
• Supports conditional formatting with --le, --ge, --bt, and --str-in-fld.
• Numeric fields are written as numbers; non-numeric fields are written as strings.

Input:

• Reads from files (stdin is not supported for binary xlsx output).
• Files ending in .gz are transparently decompressed.

Output:

• An Excel (.xlsx) file.
• Use --outfile to specify the output filename (default: <infile>.xlsx).
• Use --sheet to specify the sheet name (default: input file basename).

Header behavior:

• --header / -H: Treats the first non-empty row as header and styles it.
• When header is enabled, the header row is frozen in the output.

Examples:

1. Convert a TSV file to Excel tva to xlsx data.tsv

2. Specify output filename tva to xlsx data.tsv --outfile output.xlsx

3. Specify sheet name and header tva to xlsx data.tsv --sheet "MyData" --header

4. Apply conditional formatting tva to xlsx data.tsv --header --le "2:100" --ge "3:50"
