How do I convert a TXT file to XLSX using LetsConvert?

Upload your .txt file, select XLSX as the output format, and click Convert. The tool automatically parses each line as a row and uses the detected delimiter (tab, comma, semicolon, or pipe) to split values into columns. If your TXT file has no consistent delimiter, you can switch to 'Fixed Width' mode to manually define column breaks. The converted XLSX file will be available for immediate download.

Why should I convert a TXT file to XLSX instead of keeping it as plain text?

TXT is a universal plain-text format, but it lacks any structural meaning. Converting to XLSX organizes your data into a grid of cells, allowing you to apply Excel's features such as formulas, PivotTables, conditional formatting, and data sorting. XLSX also supports multiple worksheets, which is useful for separating data sets. Additionally, many data analysis tools and business workflows expect spreadsheet input, making XLSX the more compatible format for professional tasks.

What happens to character encoding and delimiters when I convert TXT to XLSX?

The converter preserves the original character encoding (e.g., UTF-8, ISO-8859-1) so that special characters like accents or non-Latin scripts remain intact. For delimiters, it automatically detects the most common separator used in your TXT file and maps each delimited value to a separate cell. If you enable 'Smart Data Type Detection', numeric strings are converted to numbers and date-like strings to date formats in the XLSX output, while unrecognized values stay as text. This ensures the data structure is accurate without altering the raw content.
