Export pandas dataframe to excel sheet

Question

I have a dictionary of dataframes and need to export them to excel.

mycollection = {'company1': df1, 'company2': df2, 'company3': df3}

I need to export all 3 dataframes to a single excel file using 3 sheets. Each sheet should be named the company number for e.g. "company3".

There are around 200 dataframes in the mycollection dictionary. I can use to_excel method to export data to excel, but that will create 200 excel files. Is it possible to export dataframe to sheets?

Use ExcelWriter with iter dicts and write by DataFrame.to_excel:

with pd.ExcelWriter('output.xlsx') as writer:  
    for k, v in mycollection.items():
        v.to_excel(writer, sheet_name=k)

# InvalidWorksheetName: Excel worksheet name 'XXXX_YYYY_promo_194_del_ZZZ_may2017' must be <= 31 chars.

It seems that I need to truncate long sheet names to 31 characters without duplicating! sheet_name=k[:30] may or may not always work
