What file format does UDISE+ accept for bulk upload?

UDISE+ accepts Excel files in .xlsx format (Excel 2007 and later). Files must use the official template downloaded from the portal. CSV, .xls (older Excel), and other formats are not supported for direct upload.

Why does UDISE+ show 'File format not supported' error?

This error occurs when: 1) File is not .xlsx format, 2) File was converted incorrectly (e.g., renaming .csv to .xlsx), 3) File is corrupted, 4) File was created in incompatible software. Download fresh template from UDISE+ and copy data carefully.

What is the maximum file size for UDISE+ upload?

UDISE+ typically accepts files up to 5 MB. For larger datasets, split into multiple files with maximum 500 records per file. Remove unnecessary formatting, images, and blank rows to reduce file size.

How to fix partial upload where some rows failed?

Download the error report which shows failed rows with reasons. Create a new file with ONLY the failed rows (don't include successful ones to avoid duplicates). Fix the specific errors mentioned and re-upload the corrected file.

File Format Not Supported

Error: "Invalid file format" or "Only .xlsx files accepted"

Supported vs Unsupported Formats:

.xlsx

✅ Supported

.xls

❌ Not Supported

.csv

❌ Not Supported

.ods

❌ Not Supported

✅ Solutions:

Download the official template from UDISE+ portal
Open in Microsoft Excel (or compatible software)
Save as: Excel Workbook (.xlsx) - not "Excel 97-2003"
Don't just rename file extension - actually convert the file

⚠️ Common Mistake: Renaming a .csv file to .xlsx doesn't convert it. Use "Save As" in Excel to properly convert.

File Size Exceeds Limit

Error: "File too large" or upload hangs/times out

Size Reduction Strategies:

Issue	Solution	Impact
Too many rows	Split into multiple files (500 rows each)	High
Extra blank rows	Delete all rows after last data row	Medium
Heavy formatting	Remove colors, borders, fonts	Medium
Embedded images	Remove all images from file	High
Extra sheets	Delete unused worksheets	Low
Formulas	Convert formulas to values (Paste Special)	Low

📋 Pre-Upload Checklist:

✓

Max 500 records per file

Split larger datasets into multiple files

✓

Remove blank rows at bottom

Select blank rows → Right-click → Delete

✓

Keep only essential columns

Don't add extra columns beyond template

✗

Don't embed images or objects

Logos, photos, shapes increase size dramatically

📋

Column Mapping / Template Error

Error: "Invalid column structure" or "Header mismatch"

This error occurs when the file structure doesn't match what UDISE+ expects. The portal validates column headers and order strictly.

❌ Common Template Mistakes:

Renaming column headers
Deleting or adding columns
Changing column order
Data in first row (should be headers)
Using old/outdated template version

📥 Always Use Official Template

Download fresh template from UDISE+ portal before each upload session

Go to UDISE+ Portal →

✅ Correct Approach:

Download template from portal

Go to the specific upload section and download current template

Don't modify first row (headers)

Keep all column headers exactly as provided

Enter data from row 2 onwards

First data row should be row 2, not row 1

Save without changing structure

Keep original filename format if specified

⚡

Partial Upload / Some Rows Failed

Message: "X records uploaded, Y records failed"

This is actually partial success! Some records were uploaded successfully, but others had validation errors.

📊 How to Fix Failed Records:

Download Error Report

Click "Download Error Report" button after upload - shows failed rows with specific errors

Create New File with Failed Rows Only

Copy ONLY failed records to new template. Don't include successful ones (causes duplicates!)

Fix Specific Errors

Refer to error column in report - fix exact issues mentioned

Re-upload Corrected File

Upload the new file with only corrected records

⚠️ Important: Never re-upload the full original file! Successful records will create duplicates.

⏱️

Upload Timeout / Connection Lost

Upload hangs, browser freezes, or connection error appears

Possible Causes & Solutions:

🌐

Slow/Unstable Internet

Use wired connection if possible. Avoid WiFi during upload.

📊

Large File Size

Reduce file size. Split into smaller chunks of 200-300 records.

🕐

Peak Traffic Hours

Try uploading early morning (6-9 AM) or late night (10 PM - 12 AM).

🔌

Server Issues

Wait 10-15 minutes and try again. Check UDISE+ status announcements.

💡 Pro Tip: Don't close the browser or navigate away during upload. The process may complete even if it seems stuck. Wait at least 5 minutes before retrying.

Frequently Asked Questions

Can I upload Excel files created in Google Sheets?

Yes, but you must download as .xlsx format from Google Sheets (File → Download → Microsoft Excel). Direct sharing links won't work. Verify the downloaded file opens correctly in Excel before uploading.

How do I know if upload was successful?

UDISE+ shows a confirmation message with count of records uploaded. Check the data entry section to verify records appear. Download the upload report for detailed status.

Can I upload the same file twice?

Uploading the same file again may create duplicate entries. The system may reject duplicates based on Aadhaar, but it's best to upload once and verify success.

What if upload succeeded but data is wrong?

You can edit individual records through the portal. For bulk corrections, there's no bulk update feature - you'll need to edit each record or contact Block office for major corrections.
