There are several ways you can use bibtex-tidy:
* In your browser
* CLI
* As a pre-commit-hook
* Javascript/Typescript API

Example

Before:

``bibtex
@ARTICLE {feinberg1983technique,
title={A technique for radiolabeling DNA restriction endonuclease fragments to high specific activity},
author={Feinberg, Andrew P. and Vogelstein, Bert},
journal = {Analytical biochemistry},
volume = 132,
number=1,
pages={6--13},
year=1983,
publisher={Elsevier},}
@article{miles1984qualitative,
title={Qualitative data analysis: A sourcebook},
author={Miles, Matthew B. and Huberman, A. Michael and Saldana, J.},
journal={Beverly Hills},
year=1984
}
`

After bibtex-tidy references.bib:

`bibtex
@article{feinberg1983technique,
title = {A technique for radiolabeling DNA restriction endonuclease fragments to high specific activity},
author = {Feinberg, Andrew P. and Vogelstein, Bert},
year = 1983,
journal = {Analytical biochemistry},
publisher = {Elsevier},
volume = 132,
number = 1,
pages = {6--13}
}
@article{miles1984qualitative,
title = {Qualitative data analysis: A sourcebook},
author = {Miles, Matthew B. and Huberman, A. Michael and Saldana, J.},
year = 1984,
journal = {Beverly Hills}
}
`

CLI

Requires node v12 or later.

`sh
npm install -g bibtex-tidy
bibtex-tidy references.bib

`manpage
--help, -h
Show help

--v2
Input files will no longer be modified by default. Instead, you will need to
specify --modify/-m option to overwrite the file, or --output/-o to
output to a different file.

--output, -o
Write output to specified path. When omitted (and -m/--modify is not used),
the result will be printed to stdout.

--modify, -m, --no-modify
Overwrite the original input files with the tidied result. This is enabled by
default but will be disabled by default in v2. For v1, use --no-modify to
output to stdout instead of overwriting the input files.

--omit
Remove specified fields from bibliography entries.

Examples:
--omit=id,name

--curly, --no-curly
Enclose all property values in braces. Quoted values will be converted to
braces. For example, "Journal of Tea" will become {Journal of Tea}.

--numeric, --no-numeric
Strip quotes and braces from numeric/month values. For example, {1998} will
become 1998.

--months
Convert all months to three letter abbreviations (jan, feb, etc).

--space
Indent all fields with the specified number of spaces. Ignored if tab is set.

Examples:
--space=2 (default), --space=4

--tab, --no-tab
Indent all fields with a tab.

--align, --no-align
Insert whitespace between fields and values so that values are visually
aligned.

Examples:
--align=14 (default)

--blank-lines, --no-blank-lines
Insert an empty line between each entry.

--sort, --no-sort
Sort entries by the specified field names (citation key is used if no fields
are specified). For descending order, prefix the field with a dash (-).

Multiple fields may be specified to sort everything by first field, then by
the second field whenever the first field for entries are equal, etc.

The following additional fields are also permitted: key (entry citation key),
type (sorts by the type of entry, e.g. article), and special (ensures that
@string, @preamble, @set, and @xdata entries are first).

Examples:
--sort (sort by citation key), --sort=-year,name (sort year descending then
name ascending), --sort=name,year

--duplicates
Warn if duplicates are found, which are entries where DOI, abstract, or
author and title are the same.

Examples:
--duplicates doi (same DOIs), --duplicates key (same IDs), --duplicates
abstract (similar abstracts), --duplicates citation (similar author and
titles), --duplicates doi, key (identical DOI or keys), --duplicates (same
DOI, key, abstract, or citation)

--merge, --no-merge
Merge duplicates entries. Use the duplicates option to determine how
duplicates are identified. There are different ways to merge:

- first: only keep the original entry

- last: only keep the last found duplicate

- combine: keep original entry and merge in fields of duplicates if they do
not already exist

- overwrite: keep original entry and merge in fields of duplicates,
overwriting existing fields if they exist

--strip-enclosing-braces
Where an entire value is enclosed in double braces, remove the extra braces.
For example, {{Journal of Tea}} will become {Journal of Tea}.

--drop-all-caps
Where values are all caps, make them title case. For example, {JOURNAL OF
TEA} will become {Journal of Tea}. Roman numerals will be left unchanged.

--escape, --no-escape
Escape special characters, such as umlaut. This ensures correct typesetting
with latex. Enabled by default.

--sort-fields
Sort the fields within entries.

If no fields are specified fields will be sorted by: title, shorttitle,
author, year, month, day, journal, booktitle, location, on, publisher,
address, series, volume, number, pages, doi, isbn, issn, url, urldate,
copyright, category, note, metadata

Examples:
--sort-fields=name,author

--strip-comments, --no-strip-comments
Remove all comments from the bibtex source.

--trailing-commas, --no-trailing-commas
End the last key value pair in each entry with a comma.

--encode-urls, --no-encode-urls
Replace invalid URL characters with percent encoded values.

--tidy-comments, --no-tidy-comments
Remove whitespace surrounding comments.

--remove-empty-fields, --no-remove-empty-fields
Remove any fields that have empty values.

--remove-dupe-fields, --no-remove-dupe-fields
Only allow one of each field in each entry. Enabled by default.

--generate-keys
For all entries replace the key with a new key of the form
