I have an excel file which has many rows with more than 10000 records. I need to compare two rows whether the two rows have the same value for the corresponding cell using java script.

Hi Martin! Can you explain in more detail please? Do you really need to compare two rows in Excel sheets with JavaScript? Client-side? –  slhck Jan 8 '13 at 19:07

This is an uncommon request to say the least (JavaScript + Excel?), but you're in luck:

Microsoft has released an XLSX parser written in JavaScript – and, believe it or not, it's open source:


Once the data is available as JavaScript objects, doing what you aim to do should be straightforward.

Also check out blog.innovatejs.com for similar libraries working with DOCX and ("soon") XCHG formats. –  limulus Jan 8 '13 at 19:26
As discussed (github.com/stephen-hardy/xlsx.js/issues/8) this project is definitely not open source –  Nirk Apr 10 at 22:56
