How it works

The Text Trimmer removes leading and trailing whitespace from each line in a block of text, producing clean output with no invisible padding. It can also standardize internal whitespace by collapsing multiple consecutive spaces into one.

Copy-pasted text from PDFs, spreadsheets, and web pages frequently has trailing spaces that are invisible but cause problems in code, databases, and comparison operations. The Text Trimmer is the fastest way to clean this up in bulk.

How to use it: paste your text. By default, the tool trims both leading and trailing whitespace from each line. Options: "Trim leading only", "Trim trailing only", "Trim both ends", and "Collapse multiple spaces". A line count is shown before and after to confirm how many lines were processed.

Database scenario: if you're inserting a list of user-entered values into a database without trimming, you can end up with "Alice " (with a trailing space) and "Alice" as two distinct records. This causes duplicate data and failed lookups. Running pasted data through the trimmer before import prevents this class of data quality issue.

CSV cleanup: when exporting from spreadsheets, cells sometimes contain trailing spaces, especially in text columns. The Text Trimmer cleans an entire exported column quickly before reimport.

Frequently Asked Questions

Does it trim each line individually or the whole block?
By default it trims each line individually, removing leading and trailing whitespace from every line. Toggle 'Whole block mode' to trim only the very start and end of the entire text.
Does it handle tabs as whitespace?
Yes. Tabs (\t), spaces ( ), and other Unicode whitespace characters are all treated as trimmable whitespace.
What does 'Collapse multiple spaces' do?
After trimming ends, 'Collapse multiple spaces' reduces any sequence of two or more consecutive spaces within a line down to a single space.
Does this affect line endings?
No. The trimmer removes whitespace characters at the start and end of lines but does not change the line endings themselves (LF, CRLF are preserved).
