Did you share an Excel sheet only to realize that there is a glaring typo in the title? Or worse, you may accidentally send a sheet with highly confidential salary data. Let’s be honest, we have all been there, and it’s not fun. After experiencing several such situations, I have developed a pre-sharing routine that I never skip. These are my Excel safety checks, which save me from those embarrassing (and sometimes costly) mistakes. A few simple steps will save you time, stress, and maybe even your reputation.

Why is it important?

It’s easy to think these steps are just extra work, but it is crucial to have a pre-sharing routine for your Excel sheets for several important reasons.

• It prevents errors. Even a small typo in a formula, web link, or cell can have significant consequences, especially in professional settings.
• A clean Excel sheet shows professionalism. It screams attention to detail and care in your work.
• A clear, organized spreadsheet with proper documentation makes it easier for others to understand your data.
• It protects your confidential and private information.

5 Validate your data with minute details

Data validation is like proofreading your workbook, on steroids. It ensures your data is accurate, consistent, and ready for whatever analysis you or the recipients have in mind. First, you should take care of duplicates. You can use conditional formatting to highlight them and then decide how to handle them.

You should also check spelling, capitalization, and unit of measurement. You need to clearly label your units (kg, cm, $, etc.) and ensure they are consistent throughout your sheet. It’s also important to check data logic. For example, if you have ‘Start Date’ and ‘End Date’ columns, use data validation to avoid using end dates that are earlier than start dates.

4 Make your workbook easy to read and understand

This is another important aspect you need to check off before sending an Excel file. You need to focus on clarity and usability. You should use descriptive headers for columns and rows. For example, write ‘Total Sales’ instead of cryptic abbreviations like TS.

Although Excel offers a bunch of formatting options for your workbook, you should ensure consistent font, font size, and color scheme throughout all sheets. After all, unnecessary bolding or italics can make the sheet look disorganized.

If you have a large worksheet with hundreds of rows and columns, freeze the top row or first column so they remain visible as the user scrolls. You should also explore conditional formatting to highlight essential data in your crowded worksheet. At the end of the day, it’s essential to keep the purpose of the sheet in mind and take action accordingly.

3 Add a README sheet for complex databases and formulas

Not everyone is an Excel pro, and your recipient may face issues navigating the sheet or executing formulas. Here is where a dedicated README sheet comes into play. It clearly states the purpose of the spreadsheet and the key insights it provides. You can also write down step-by-step instructions on how to use the spreadsheet, especially if there are interactive elements or macros.

If certain cells rely on specific assumptions, use cell comments from the right-click menu. A red arrow should appear on such cells. This empowers users to understand your data, trust your analysis, and make informed decisions.

2 Remove hidden and personal data

Before you hit the ‘Send’ button, take a moment to spot hidden or personal data in your workbook. Hidden worksheets, rows, and columns may contain confidential data like financial details, employee records, or proprietary formulas.

Such hidden formulas may disclose sensitive calculations or data sources. You can use Excel’s Document Inspector or manually review it to identify and remove hidden data as needed.

1 Password-protect and set an expiry date for an Excel workbook

Sharing your confidential workbooks always comes with risks. Suppose you are a sales manager and want to send quarterly numbers to your team. Here, you wouldn’t want marketing, social media, and other departments to glance over such numbers, would you? Here is where OneDrive’s handy features come to the rescue – namely, password protection and expiry dates.

They act as security guards for your data and ensure that only authorized people can access your files, and that too for a limited time. First, you need to upload the file to the OneDrive platform, hit the Share button at the top, pick permission options, and enter a password and expiry link.

Must-do Excel checklist

And there you have it! Implement my tried-and-tested routine for prepping Excel sheets before sharing them with the world (or with your boss). It may seem like a daunting task at first glance, but trust me, the payoff is worth it. Also, if you have enabled automation in your Excel workbook, make sure to run it twice before hitting the send button.
