Frequently Asked Questions
How to convert a text file to Excel with columns automatically?
Upload your .txt file or paste your raw text into the converter. The smart auto-detector will scan your text structure and determine whether fields are separated by tabs, commas, semicolons, pipes, or fixed-width spacing. The data is instantly mapped into organized spreadsheet columns and rows, ready to download as a .xlsx workbook.
Why are my leading zeros preserved when converting to Excel?
Standard Excel imports often destructively convert numeric strings like ZIP codes (e.g. '01234') into integers ('1234'), dropping the leading zero. Our converter includes a 'Preserve leading zeros' setting that marks identifier codes as text cells, ensuring account numbers, part numbers, and postal codes remain intact.
Is my text data uploaded to a server during conversion?
No. All text parsing, table rendering, and Excel spreadsheet generation happen 100% locally inside your web browser using client-side JavaScript. Your text and sensitive data never leave your computer.
Can I convert fixed-width or space-aligned text files?
Yes. Select the 'Fixed Width' or 'Space' delimiter option. The parser evaluates column boundaries across all lines so spaces inside descriptive text (such as product names or addresses) are not mistakenly split into separate columns.
What text file formats are supported?
The converter supports plain text (.txt, .text), comma-separated values (.csv), tab-separated values (.tsv), data files (.dat), print reports (.prn), and server log files (.log).
