How to convert TXT to CSV
Plain text files sometimes contain tabular data separated by tabs, spaces, pipes, or other delimiters. Converting a TXT file to CSV formats the data with comma separation so it can be opened directly in Excel, Google Sheets, or imported into a database.
BoltConverter parses your text file on its servers and outputs a properly formatted CSV. The converter detects common delimiters (tabs, pipes, multiple spaces) and normalizes them to commas. The resulting .csv file is ready for spreadsheet import.

Frequently asked questions
What delimiters does the converter recognize?
Tab, pipe (|), semicolon, and multiple-space delimiters are commonly detected and converted to commas. If your file uses an unusual delimiter, results may vary.
What if my text has commas inside values?
If text values contain commas, the converter should quote those values in the CSV output. If the quoting is incorrect, the CSV may need manual cleanup in a text editor.
Can I convert a fixed-width text file to CSV?
Fixed-width files where columns are aligned by position rather than a separator are harder to convert automatically. You may need to specify column positions in a dedicated tool.
Will the first row be treated as headers?
If the first row of your text file contains column names, those become the header row in the CSV. The converter treats the file structure as-is.
Can I open the CSV in Google Sheets directly?
Yes. Upload the CSV to Google Drive, then open it with Google Sheets. Google Sheets automatically detects the comma delimiter.
