- Excel to Latex table converter
My favorite online converter is now offline! I love it for its simplicity and ease of use. For now, interested users can download the Excel2LaTex.xla package. To install, go to the "options" setting under the File tab in Exel (2010) and choose "Add-Ins" from the left panel. Click on the "Go" button next to Manage Excel add-ins. Then browse and select the downloaded .xla file. Now you can convert the table to Latex under the Add-ins tab in Excel.
