How to Convert TXT to Excel (.xlsx) Online
Converting raw plain text data into a structured Microsoft Excel spreadsheet (.xlsx) allows you to perform calculations, build pivot tables, apply formulas, and create charts. Follow these simple steps:
Input Text or File
Drag and drop your .txt, .csv, or .tsv file into the upload zone or paste raw text directly into the text editor.

Common Text Delimiters & Spreadsheet Formats
Understanding the differences between text formats commonly imported into Excel:
| Format / Delimiter | Symbol | Typical File Extension | Primary Use Cases |
|---|---|---|---|
| CSV (Comma-Separated) | , | .csv, .txt | Standard data exports, e-commerce orders, contacts, CRM databases. |
| TSV (Tab-Separated) | \t (Tab) | .tsv, .tab, .txt | Copy-pasting directly from web tables, database queries, bio-informatics. |
| Semicolon-Separated | ; | .csv, .txt | European accounting software where comma is used as the decimal separator (e.g. 19,95 €). |
| Pipe-Delimited | | | .dat, .txt, .log | System logs, mainframe dumps, healthcare records (HL7/EDI), complex nested records. |
| Space-Delimited | ␣ (Space) | .prn, .txt | Server access logs, terminal reports, columnar fixed-width print captures. |
- Preserving Leading Zeros: If your text data contains telephone numbers, postal codes, or product SKUs (such as
004829), toggle on the "Preserve Leading Zeros" switch to prevent Excel from converting them into bare integers (4829). - Quotes & Text Qualifiers: If your cells contain commas inside sentences (e.g.
"Los Angeles, CA"), wrap them in standard double quotes so the parser does not split them into two separate columns. - Multi-Sheet Workbooks: Upload multiple text files simultaneously to produce a consolidated Excel workbook where each text file becomes an individual, properly labeled sheet.
