BibTeX to JSON Converter
Processing entirely on your device — large files may take a moment.
Convert tables to JSON when a website, app or API expects structured records with named fields. If your files are still in BibTeX format, this page is the shortcut: BibTeX is the bibliography format of the LaTeX world — @article and @inproceedings entries that every academic paper cites from. Decades of scholarly references live in .bib files.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How BibTeX compares to JSON
| BibTeX | JSON | |
|---|---|---|
| Structure | @type entry blocks | Trees of objects and arrays |
| Compatibility | LaTeX, arXiv workflows | Universal, machine-first |
| Best for | Academic bibliographies | APIs, app data, config-as-code |

About the BibTeX format
BibTeX is how the LaTeX world stores citations: @article{key, author={...}, title={...}} entries that cite commands resolve into bibliographies. Decades of academic writing live in .bib files, and the arXiv-to-paper workflow depends on them.
Converting BibTeX to JSON makes citation data queryable for dashboards and review tooling; converting to RIS hands it to Zotero or Mendeley users without LaTeX in the loop.
+Strengths
- ✓Standard of the LaTeX ecosystem
- ✓Decades of accumulated references
!Limitations
- −String concatenation syntax is fiddly
- −No official specification document
About the JSON format
JSON (RFC 8259, popularized by Douglas Crockford) is the lingua franca of program data. It has exactly six types — string, number, boolean, null, array, object — nested into trees, and every language on earth parses it natively. REST APIs, NoSQL documents, browser configuration, package manifests: if software talks to software, JSON is usually the sentence.
The spec is deliberately strict: double quotes only, no trailing commas, no comments. That rigidity makes parsers trivial and interop reliable, but it also makes JSON awkward for hand-edited config (people bolt comments on and break parsers) and its 1:1 text mapping keeps large files heavier than binary alternatives.
+Strengths
- ✓Native parsing in every language
- ✓Six clear types, nesting as deep as needed
- ✓The default of APIs and modern tooling
!Limitations
- −No comments — poor fit for hand-edited config
- −Strict syntax: trailing commas and single quotes break it
- −Verbose; large files parse slowly
Why convert BibTeX to JSON?
Converting makes sense where the strengths of JSON meet what BibTeX cannot give you. Native parsing in every language Meanwhile String concatenation syntax is fiddly One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this BibTeX to JSON converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for BibTeX to JSON?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does the conversion work offline?
Yes. Once the page has loaded, the conversion itself runs entirely inside your browser — you can even disconnect and keep converting. No file ever touches a server.
Can I edit the JSON result afterwards?
That depends on the target: JSON is designed for what it does, and this converter reproduces its content faithfully rather than inventing editable structure. For heavy re-editing, work from a format built for editing and export the final version here.
